Debunking 3 Running Dehydration Myths

dehydration and running performance

Myth One: If you don’t have clear wee you are dehydrated.

The fact of the matter is, if your wee is clear, you are likely over hydrating, or you may have kidney problems, diabetes, or other health issues.

Your body is very clever. It can defend itself against dehydration by changing the amount of water it retains. If it is retaining water, then your urine will be darker in colour. And if your urine is darker in colour because your body is retaining water, that can be a good thing. It means your body is working well to remain hydrated. Conversely, if you have more fluids than your body needs, it will rid itself of the extra water in your urine, making it less concentrated. The more we drink, over and above what our needs are, the more we wee, and the clearer our wee will be. Studies that have looked at blood markers of hydration have found the colour of your wee does not necessarily correlate with dehydration (that is, a blood sodium level of over 145 mmol/L.

As far as wee colour goes, something not clear, and not dark as tea, is where you want to be (as long as you have no medical conditions which will effect your hydration status). If you do have persistently dark wee, or persistently clear wee which can’t be explained by the amount you drink, you should see a doctor.

Myth Two: If you don’t drink water during a race, your performance will suffer

Used to be, people would say if you wait until you’re thirsty to drink, it’s too late-you’re already dehydrated and your performance has already been impaired. It seems that the body can cope much better with temporary dehydration than was previously thought. Taking water on board based on how you feel is more important than replacing every drop of fluid you use.

A couple of recent studies highlight this well.

One study had 23 female recreational runners do two 15km time trials, in mild, but humid conditions (68 degrees F/ 20 degrees C,  87% humidity). In one of the trials, they drank 12 oz of water during the run (about 350mls), and in the other they simply rinsed their mouths with water and spat it out, every 3kms.

The results were interesting. The time trial results of the two groups were pretty much the same – the drinking group averaged 79.8 mins and the mouth wash group averaged 79.7 minutes for the 15k. The drinking group sweated more, and the mouthwash group felt thirstier after the run. The study also looked at a group of responses called “affective responses”, which looked at things like pleasure, arousal, energy, calmness and tension. Again, the responses were fairly similar on most measures, but the mouth wash group did report more tension.

So, under these conditions the runners didn’t need to consume water to maintain performance. Note that the temperature was fairly mild. It’s not at all unusual in Australia to be running in much hotter temperatures. I’m not suggesting you shouldn’t drink if you feel like you need to. I am suggesting that we don’t need to drink as much as we think we do, and if your gut feels like it can’t handle any more water, you could just try rinsing and spitting instead. You might actually be better off pouring the water over your head to cool you off!

A 2010 study (sponsored by gatorade) compared runners over a series of four trail runs. One group drank 200mls of water in the 22 hours prior to the runs, and no water during the runs, and the other group went into the runs well hydrated, and drank during each run. The results showed impaired performance for the non drinkers. Note that these runners with impaired performance started the run already dehydrated, as compared to the other studies which were done with runners who had normal hydration levels prior to the experiment.

Myth Three: Loss of body weight during a run means you are dehydrated and your performance suffers

Changes in body weight when you are exercising hard are not only caused by fluid loss. You burn fuel when you run, and when that fuel is used up, then you weigh less. As your race or training run progresses and you use up stored carbohydrate and fat your weight will drop. Not only that, as you burn calories during your run, you’ll also be liberating some water, which becomes available to you body. Another fact to consider is that as you lose body weight during a run due to fuel burning and fluid loss, your lighter weight will enable you to run faster – up to a certain point of course.  You don’t want to deliberately dehydrate yourself in a bid to lose body weight to help you run faster!  I’m just saying that all these little things add up to going some way to explaining why reduced body weight is not the best predictor of performance. The purpose of drinking during exercise is to keep your blood plasma levels stable, not to keep your body weight stable.

A 2016 study had well trained athletes run a 20k time trial in the heat. One group drank as much as they wanted to during the run, the other drank a set amount of fluids based on pre-determined individual needs, designed to replace as much of their sweat loss as possible.

The “drink when you want” group lost 2.6% of their body weight, whilst the well hydrated group lost only 1.3% of their body weight during the time trial. As you’d expect, the group who were drinking deliberately lost less body weight than the “drink when you want” group. Nothing to see there. But here’s what’s interesting. The performance of the groups was very similar. The hydrated runners averaged 1:44:39, and the “drink when you want” runners averaged 1:44:09. There was no difference in core temperature between the two groups at any point.

Haile Gebreselassie, one time marathon world record holder and all out running legend lost 9.8% of his body weight when he won the Dubai marathon in 2009. One study looked at the fluid intake of 9 major city marathon winners, and 1 second place getter.  It showed a body weight loss of between 6.6% and 11.7%, including including Gebreselassie’s 9.8% loss in 2009. Seems you can get some pretty good results, even if you lose quite a bit of weight during a race!

A Few Tips on Hydration

  1. Drink water when you are thirsty, all of the time, not just when you are running. That way you’ll go into a run well hydrated.
  2. For runs of 60 minutes or less, it seems you probably don’t need to drink much, if at all, unless the conditions are hot and humid. What feels “hot and humid” to you will depend on the weather conditions you are used to running in, your age, and your body size and composition.
  3. Experience will help you find the ideal hydration strategy for you. Around 500mls of water each hour once your runs are longer than 60 mins is a good starting point.
  4. Drink when you are thirsty during your run – water availability permitting. You might find you have to be a bit flexible on this if you are not carrying water with you.
  5. Choose a route where you know there will be water available to you, or do a loop course and stash a water bottle somewhere, or leave it in your car.
  6. If you plan to carry fluid with you in a race, it’s a good idea to train with what you are going to carry to get used to how it feels.

5 Quick and Easy Barbecue Recipes


Tandoori Chicken

So quick and easy. You just need to plan far enough ahead to marinate the chicken for a couple of hours before cooking.

I haven’t tried this one, but it looked so interesting I had to throw it in!

Refreshing Watermelon Salad, with Feta Cheese and Olives

Quick and Healthy Barbecue Recipe 1

This one has become a personal favourite of mine since discovering it a couple of years ago.

Easy Bar-B-Q Tandoori Chicken




  • Pataks Tandoori Paste ( this seems to work better than other brands)
  • Full Cream Plain Yoghurt
  • Chicken Thigh Fillets (using things will ensure a more succulent finished product)


  1. You can prepare the chicken in two ways. Either keep the thigh fillets whole, if you’re serving them as part of a sit down meal, otherwise you can cut into bit-size strips which go down very well as finger food.
  2. Prepare the tandoori paste as directed on the jar.
  3. Add the chicken. Marinating overnight gets best results, but a couple of hours will do it.
  4. Heat the barbecue plate so it is really hot when you add the chicken to seal in the juices.
  5. Put the chicken on the barbecue plate. Turn as needed. I like to cook so that parts of the chicken are just barely beginning to turn charred.

Serve with lemon wedges, and sprinkled with coriander.



7 Food Labelling Tricks

Are you being duped by food marketing?

Fat free and 100% natural: seven food labelling tricks exposed

Sandra Jones, University of Wollongong

If you’re confused by food labels, you’re not alone. But don’t hold your breath for an at-a-glance food labelling system that tells you how much salt, fat and sugar each product contains. Australia’s proposed “health star rating” labelling scheme was put on hold in February, following pressure from the food industry. And it’s unclear whether the scheme will go ahead.

Marketers use a variety of tricks to make foods seem healthier and more appealing than their competitors, particularly when it comes to products aimed at children. One of the most powerful advertising tools a food manufacturer has is the packaging, as it’s what we look at immediately before deciding which food to purchase.

Next time you’re shopping for food, look out for these seven common labelling tricks:

The colour of food packaging can influence our perceptions of how healthy a food is.

A recent study found consumers’ perceptions of two identical chocolate bars were influenced by the colour of the nutrition label; despite the identical calorie information, people perceived the one with the green label to be healthier.

Another tool of savvy food marketers is the use of “ticks” and “seals” that we subconsciously process as indicating that the product has met some form of certification criteria.

A recent study found that nutrition seals on unhealthy food products increased perceptions of healthiness among restrained eaters. And a study with parents of toddlers found 20% of parents identified the presence of a quality seal as one of the reasons for their purchase of toddler formula rather than cow’s milk.

Food packaging often contains words that imply the food contains certain ingredients, or has been prepared in a way, that makes it healthier (or at least better than similar foods).

But many of the words – such as “healthy” or “natural” – have no legal or formal meaning. While the Australian New Zealand Food Standards Code regulates the use of specific health and nutrient content claims, it doesn’t regulate or define these loose terms.

“Weasel claims” describe modifiers that negate the claims that follow them. This allows manufacturers to avoid allegations of breaching advertising or labelling regulations, while being such a commonly used word that it is overlooked by the consumer.

For example, Activia “can” help to reduce digestive discomfort – but did you read the fine print? It “can” help if you eat it twice a day and “… as part of a balanced diet and healthy lifestyle”.

Similarly, Berri Super Juice contains antioxidants which “help” fight free radicals (but so does whole fruit, which also contains more fibre).

Unfinished claims tell us the product is better than something – but not better than what. In food labelling, we really have to hunt for the “what”.

Fountain’s Smart Tomato Sauce still contains 114mg of salt per serving, while the brand’s regular tomato sauce contains 186mg (more than several other brands).

The Heart Foundation defines low-salt foods as those with less than 120mg per 100g; Fountain’s Smart tomato sauce has 410mg per 100ml. It does, however, have less sugar than many of its competitors.

So, if you are trying to reduce your sugar intake it may be a good choice, but if you are trying to reduce your sodium intake, look for one of the low-salt varieties and read the label very carefully (reduced is rarely synonymous with low).

Smiths’ Thinly Cut potato chips contain 75% less fat than “chips cooked in 100% Palmolein Oil”. But they don’t contain less fat than Original Thins, Kettle, or most other brands on the market.

It’s also worth taking a close look at the recommended serving size – in both cases the nutrition information is based on a 27g serving, but Smiths’ “single serve” pack is 45g (15.7g fat; one-fifth of an average adult’s recommended daily intake, or RDI).

A common strategy is to list a claim that is, in itself, completely true – but to list it in a way that suggests that this product is unique or unusual (when in reality it is no different to most foods in that category).

“All natural” and “no artificial colours and flavours” are appealing features for parents looking for snacks for their children. But most standard cheeses (including many packaged products such as cheese slices) also contain no artificial colours of flavours.

This is not to suggest that Bega Stringers are a bad product or that you shouldn’t buy them – just that you may want to think about the cost per serve compared to other cheeses that are equally healthy.

Like most lolly snakes, Starburst snakes are “99% fat free”. The old adage of “salt-sugar-fat” holds here; products that are low (or absent) in one are typically very high in another. In the case of lollies, it’s sugar.

As with the potato chips above, serving size is important. Those of us who can’t resist more than one snake might be surprised to realise that if we ate half the bag, we would have consumed two-thirds of our daily sugar intake (although we can’t blame the pack labelling for that!).

Sun-Rice Naturally Low GI White Rice illustrates this use of technically correct claims. Let’s start with “cholesterol free” – this is totally true, but all rice is cholesterol free.

The pack also states in very large, bright blue letters that it is “Low GI”. In much smaller letters that almost disappear against the colour of the package is the word “naturally”. This use of different colours to attract, or not attract, attention is a common marketing technique.

The product is indeed low GI, at 54 it is just below the cut-off of less than 55. But the “naturally” refers to the fact that what makes it low GI is the use of basmati rice rather than another variety, and other brands’ basmati rice would have a similar GI.

Berri Super Juice proudly, and truthfully, claims it “contains no added sugar”. You may conclude from this that the sugar content is low, but a closer look at the nutrition information label may surprise you – a 200ml serve of this super juice contains 25.8g of sugar (29% of your recommended daily allowance).

While contentious, some have even suggested that there is a link between fruit juice and both obesity and metabolic disease, particularly for children. A better (and cheaper) way of obtaining the fruit polyphenols is to eat fruit.

Healthy sounding words are not only used as “claims” but are often used as brand names. This first struck me when I was looking for a snack at my local gym and noticed the “Healthy Cookies” on display; they had more sugar, more fat and less fibre than all of the others on sale (Healthy Cookies was the brand name).

Brand names are often seen as a key descriptor of the nature of the product. Research has found that people rate food as healthy or unhealthy based on pre-existing perceptions of the healthiness of a product category or descriptor, particularly among those who are watching their diet, and may thus select the unhealthier option based on its name or product category.

If, for example, you’re watching your weight, you may be attracted to the Go Natural Gluten Free Fruit & Nut Delight bar, assuming that it will be a healthier choice than a candy bar. But you might be surprised to note that it contains 932 kJ (11.0% of your RDI) and a whopping 13.6g of fat (10% of your RDI).

A 53g Mars bar contains slightly more calories (1020kJ) but a lot less fat (9.1g), although the Go Natural bar could argue for “healthier” fat given the 40% nut content.

So, can we really distinguish between healthy and unhealthy foods by looking at the wrappers?

The healthiest wrappers are made by nature, from the simple ones that can be eaten after washing (like apples and carrots) to those that need some disposal (like a banana or a fresh corn cob).

If you are buying your food wrapped in plastic or paper, it’s a little more complex. We need to see past the colours, pictures and cleverly-crafted claims and take a careful look at the ingredients and nutrition panel.

Simplest Ice Cream Recipe Ever

Simplest Ice Cream Recipes Ever

Of course we rarely ever eat ice cream in our house… but when we do, we definitely make the most of it with the simplest ice cream recipe ever. You can add whatever flavour you like to the base of cream and sweetened condensed milk. Here are some of our favourites.

This is definitely a sometimes food!!

Coffee Icecream

The original, and some in our household say the best!


  • 1 * 600 ml thickened cream
  • 1* 400 gm tin sweetened condensed milk
  • 1-2 tablespoons chicory and coffee essence (taste after the first tablespoon and add more to taste)


  • Beat all the ingredients together-using a handheld electric mixer is simplest – you can mix it in the bowl you’re going to serve the ice cream in, as long as you can cover it in the freezer.
  • Place in the freezer, take out and re-beat every 1-2 hours to prevent it from going icy-depends a bit on how quickly your freezer freezes.
  • Make sure you go out for a run between beatings to make room for those extra calories you’ll be packing in!

Berry Ice Cream

Substitute the coffee and chicory essence for a mix of your favourite berries. Make sure you blend the berries first so the flavour.

You’ll need to be vigilant about beating whilst the ice cream is freezing. Due to the water content of the berries, it does have a tendency to ice up.

Vanilla Bean Ice Cream

Split a vanilla bean, scrape out the seeds and add to the cream and sweetened condensed milk. I also chopped the pod roughly into big pieces and threw that in, but be careful not to serve anyone these pieces. I haven’t tried it, but I think it would work best if you leave the mixture in the fridge for an hour or 2 before freezing, to let the vanilla bean seeds infuse the creamy mixture with their aromatic flavour.

It’s a toss up between vanilla bean and chili choc for my favourite.

Chili Choc Ice Cream

You can buy bars of Lindt dark chocolate and chili, but when I made this mixture, I didn’t find it hot enough. The combination of the dairy and the cold temperature has a rather cooling effect on the fiery chili. I usually add heaps of chopped chili to the chocolate mix.

Melt dark chocolate – I just used a regular chocolate bar, not cooking chocolate, chop some chili -your spice tolerance will determine how much chili and whether or not you chuck in the seeds. Mix with the cream and sweetened condensed milk.

Pine Lime Ice Cream

Add crushed pineapple (very well drained if you are using a tin) and lime cordial or lime flavouring to the cream mixture, and you have your very own splice. Another one which requires quite a bit of blending during the freezing process, both to prevent it from icing up, and to stop the pineapple from settling on the bottom.

There’s almost a limitless number of variations on this amazingly simple ice cream recipe. Have some fun, and create.

Watermelon Salad

Quick and Healthy Barbecue Recipe 1

Refreshing Watermelon Salad, with Feta Cheese and Olives

I first went searching for  a similar recipes when one of our runners brought watermelon, feta and black olive canapes along to a post running session Christmas celebration. This recipe comes from Nigella Lawson.

It’s super simple, and everyone loves it. Having said that, I do have a few exceptions in my family -my mother is not a watermelon fan, my husband can take it or leave it, and my sons think olives are “disgusting”, but other than that, everyone loves it!!

The Easy Version

Serve chunks of watermelon with black olives on a plate, sprinkled with feta and mint, with a splash of lime juice.

The Full Version

  • 1 small red onion
  • 4 limes
  • 1.5 kilograms watermelon (sweet and ripe)
  • 250 grams feta cheese
  • 1 bunch fresh flatleaf parsley
  • 1 bunch fresh mint (chopped)
  • 4 tablespoons extra virgin olive oil
  • 100 grams pitted black olives
  • black pepper

Cut the red onion into very fine slivers, put in a bowl with the lime juice. The juice of a couple of limes should do.

Cut the watermelon into triangular chunks, about 4cm each side. Cut the feta into 4cm triangles. Put them both into a wide, shallow bowl.

Add chopped mint and torn parsley.

Tip the onions and the juice over the salad bowl, add oil and olives.

Toss using your hands gently so that the feta and watermelon keep their shape.

Add cracked pepper, and more lime juice if you like.

Quick, easy, yummy, and VERY SUMMERY!


Swallowing Flies When You’re Running

swallowing a fly when you're running

We’ve all been there. Running along happily, breathing through your mouth, or perhaps having a chat with a fellow runner, and wham! A disgusting flying creature decides to take a closer look at your mouth. Think about the poor fly!!

We got to talking about flies last night after a particularly warm, fly infested session, and what actually happened to the fly after it entered your body.

How long would it survive? Where does it actually go. I’ve always assumed we swallowed them, but someone suggested we are inhaling them, which sounds reasonable. Sometimes it seems as if your mouth is a vacuum when you’re running and breathing hard. Watch out any suckers that get in it’s way! Must be pretty scary being sucked into a dark smelly tunnel with no chance of escape.

Inhaling or Swallowing?

I’d always assumed that when a fly went into my mouth, my epiglottis would close over my larynx (which leads to the lungs), and I’d just swallow it. It would then fly around a little bit on the way down to a painful death at the hands of the hydrochloric acid in my stomach. Serves it right, I reckon. It’s disgusting swallowing a fly!
Bodybuilding recipes – spice up that chicken! – Body Spartan clenbuterol tablets anabolic-androgenic steroids and bodybuilding acne, are steroids for bodybuilding dangerous – food and environment safety analytical laboratory
But thinking about it a little bit more, it’s quite possible the fly is inhaled. They dart into your mouth when you are least expecting it. That means your brain doesn’t know that it should be getting the mechanisms in your mouth ready to swallow. The epiglottis will be open, allowing you to breath whilst you’re running. Closing the epiglottis and performing the action of swallowing, requires the activity of about 30 different muscles. Even though they activate in less than a second, unless your brain knows to signal to these muscles to swallow, anything that’s sucked into your mouth unexpectedly is likely to head down your larynx, at least for a short while.

Will An Inhaled Fly Go Into Your Lungs?

It’s not very likely that the fly will get very far. The far more likely scenario is that you’ll cough like crazy (in fact you might feel like you’re coughing your lungs right up). The offending fly will then be coughed into your mouth along with a bit of mucus which has entombed the fly in order to stop it from proceeding down the larynx, and then you’ll swallow it. Much the same as would happen if you had a piece of food “go down the wrong way”. Your body’s cough reflex will help you to get it out of your airways so that you can breathe freely again.

If you’re sure that the fly’s gone down your windpipe, and you don’t see it come out again when you cough, it’s much more likely that it has come out into your mouth and you’ve swallowed it. It’s not like you’re going to cough it up, open up your mouth, and see it fly away free again (only to bug the next unsuspecting runner who comes along).

How Long Will A Fly Live For Inside You?

I have no idea on this one, but I have seen someone perform a circus act where they swallowed a live gold fish, vomited it back up and it was still alive. Absolutely gross, and probably too much information, but I think it means the fly would probably live for at least a little while inside you before it died. Eventually it will go the way of all good waste products, out to Bondi, which for those of you not in the know, is where a large percentage of the sewerage generated by those living in our fine city of Sydney is treated before being dumped into the ocean.

So your fly, will eventually become a swim!!
