The Short Answer: Race Morning Schedule
Begin your 5k or 10k warm up 40 minutes before the gun. Do a 5-10 minute easy jog, 5–10 minutes of dynamic stretching, and 3–4 x 20-second strides at 95% of 5k race pace. Finish 5–10 minutes before the start.

Why Warming Up Matters for Shorter Races
Unlike a marathon or half marathon — where the first few kilometres essentially serve as your warm up — a 5k or 10k demands that you’re ready to go hard from the gun. These races hurt from the start. Your heart rate spikes quickly, your legs need to turn over fast, and there’s very little time to “ease into it.”
Skipping your warm up for a 5k or 10k doesn’t save energy — it costs you performance. A good warm up before running prepares your body by:
- Increasing blood flow and oxygen delivery to your working muscles.
- Raising your core body temperature for more efficient muscle contraction.
- Lubricating joints and tendon sheaths to reduce injury risk.
- Improving neuromuscular communication (brain-to-muscle) for better power and stride efficiency.
- Settling pre-race nerves and getting you mentally locked in.
The 20-Minute Explosive 5k/10k Routine
This 20-minute explosive warm-up is designed to prevent ‘first-mile shock,’ raise your core temperature, and prime your neuromuscular system for peak performance in a 5k or 10k race.
Start this routine 30-40 minutes before race time. This allows time for a toilet stop and ensures you get to the starting corral without stress. If it’s a large race, aim for 40 minutes before the gun to account for longer toilet queues and crowded start precincts.
Use this routine in training – try it for at least a couple of your harder workouts pre race-day. The golden rule is never to try anything new on the day of the event!
Phase 1: Easy Jog (5 to 10 Minutes)
Begin with a very easy 5-10 minute jog. This should feel genuinely comfortable—almost embarrassingly slow. The goal is simply to get your blood moving, raise your body temperature, and shake the stiffness out of your legs
Phase 2: Dynamic Activation Drills (5 to 10 Minutes)
Now is the time for light dynamic movement to wake up your running mechanics. Avoid prolonged static stretching (holding a stretch for 30+ seconds) before the race, as this can actually reduce muscle power output.
Focus on these drills over a 20-meter stretch:
- Leg swings (forward/back and side-to-side) to loosen hip flexors and glutes.
- Ankle rotations to warm up the lower leg.
- High knees: Fast feet, high turnover. Aim to lift your foot again as soon as it hits the ground.
- Butt kicks: Focus on quad stretching and quick hamstring curls.
- Walking lunges (forward and reverse) to activate quads, hamstrings, and glutes.
- Lateral Lunges: 5 per side to wake up the adductors.
Phase 3: The “Neural Priming” Strides (5 to 10 Minutes)
This is the most important part for a fast race, yet it’s the part most recreational runners skip. Strides “prime” the nervous system to handle race-pace turnover.
The Routine: Perform 3–4 x 20-second strides. Start at a jog and build pace over 50 meters until you reach approximately 95% of your 5k race pace. Walk back slowly between each effort (60–90 seconds rest).
Phase 4: Final Prep and The “Gap” Strategy
After your strides, make a loo stop and then keep yourself warm. If the weather is cool, wear a “throwaway” layer into the start corral. Don’t let your body temperature drop while standing around.
A Note on Large Fun Runs: If space is limited, do as much of the routine as you can. Prioritize the easy jog and the strides (even in a side street near the start). An abbreviated warm up is far better than none.
Pro-Tip: Managing the Start Corral Delay If there is a delay between your warm up and the gun:
- Keep the Engine Running: Do small hops on the spot or “patter” your feet (very fast, small steps) every 2 minutes.
- Don’t Sit Down: Sitting tells your nervous system to “shut down.” Keep muscles “snappy.”

Frequently Asked Questions
How long should a 5k warm up be?
Your actual running warm up should take around 20–25 minutes. However, you should begin the process 40 minutes before gun time to account for a toilet stop and getting into the starting corral.
Should I warm up before a 10k race?
Yes. A 10k is run at a high intensity almost immediately. Without a warm up, you lose time in the early stages while your body catches up, or you risk going out too hard “cold” and blowing up later.
What is the best warm up for a fast 5k?
The single biggest upgrade is adding race-pace strides. 3–4 x 20-30 second efforts building up to race pace prime your neuromuscular system to fire from the very first metre.
Can I warm up before a 5k race by just jogging slowly?
A slow jog is a good start, but it is not enough for a race. It raises core temperature, but dynamic drills and strides are needed to prime your muscles for the specific intensity of race pace.
Is it okay to skip the warm up for a 5k or 10k race?
If you are racing for a time, skipping the warm up means a slower start, leaving time on the table, and a higher injury risk.
