5K race week: a day-by-day guide

By the Faster5K team · Updated November 8, 2026 · 4 min read

The hard work is done. The goal of race week is to arrive at the start line rested, sharp and with a clear plan. You can't gain much fitness in the final days, but you can easily lose your race to fatigue, nerves or a bad breakfast.

The principle: less volume, a little intensity

For a 5K, a short taper of about a week works for most recreational runners. Cut your total running by roughly a third to a half compared with a normal week, but keep a little faster running so your legs stay sharp. Cutting all intensity tends to leave people feeling flat and sluggish on race day. What you're aiming for is fewer and shorter runs that still include some quick ones.

Day-by-day plan (Saturday race)

If you only run three days a week, keep Tuesday's race-pace session and one easy run, and rest the other days.

What to eat

A 5K is short enough that carbohydrate loading isn't necessary. Your normal balanced diet already stores enough glycogen for 15–40 minutes of hard running. What matters more is not upsetting your stomach.

• The days before: eat normally. Drink regularly so your urine is pale.
• The night before: a familiar meal. Not the evening to try a new spicy restaurant or eat a huge amount.
• Race morning: something light and familiar 2–3 hours before the start, such as toast, oatmeal or a banana, plus water. If you usually run before breakfast and feel fine, that's OK too. Coffee is fine if it's part of your routine.
• During the race: most runners need nothing. On a hot day, take a sip at a water station if there is one.

Know your pace

Decide on a goal based on training, not hope. If you've done the work for 25:00, go for 25:00, not 23:30. Look up your per-km or per-mile pace on the 5K pace chart and get checkpoint times from the split calculator. Write the first two split times on your hand if that helps.

Have a plan B. If it's hot, windy or hilly, add a few seconds per km to your target from the start rather than finding out at 3 km.

Race-morning checklist

• Arrive 45–60 minutes early. Queues for toilets and bib pick-up are the most common cause of a rushed warm-up.
• Warm up: 10–15 minutes of easy jogging, a few dynamic drills (leg swings, skips), then 3–4 strides building to race pace. Finish the warm-up 5–10 minutes before the start.
• Line up with runners of a similar pace. Starting too far forward drags you into a fast first kilometre; too far back means weaving.
• Start your watch as you cross the start mat, not at the gun.

Running the race

First kilometre: it will feel easy. That's normal and a trap. Run at goal pace, or a couple of seconds slower. Check your first split: if you're more than 5 seconds per km fast, ease off immediately.

Kilometres 2–3: this is where 5Ks are won and lost. Effort rises while pace stays the same. Focus on the runner ahead, relaxed shoulders, quick light steps.

Kilometre 4: it hurts now. Hold on, break it into small pieces: to the next lamp post, the next corner.

Last kilometre: if there's anything left, use it here. Start pushing at about 4 km, and empty the tank in the final 200–300 m.

Nerves

Pre-race nerves are normal and partly useful: they're your body getting ready to perform. Reduce the uncertainty you can control (logistics, kit, plan) and accept the rest. A good warm-up is also one of the best ways to settle nerves.

Common race-week mistakes

• Cramming a big workout. A hard session 2–3 days before the race leaves fatigue but adds no fitness you'll notice in time. If you missed a key workout, let it go.
• Testing yourself. Running a "practice 5K" at full effort a few days out is the most common version of this. Save it for the race.
• Doing nothing at all. A full week of rest often leaves legs feeling stale. Short, easy runs with a few strides keep you sharp.
• New kit. New shoes, socks or shorts on race day can mean blisters or chafing. Wear what you've trained in.
• Late nights. One poor night before the race usually won't ruin it, but a week of short sleep can. Prioritise sleep all week, so pre-race nerves on the last night matter less.

After the race

Keep walking for a few minutes, drink something, and eat within an hour or two. Take one or two easy days. Then put your new time into the race time predictor and training pace calculator for updated numbers, and decide on your next goal.

Don't race if you're unwell with a fever or chest symptoms. Running hard while ill is not worth it, and there will be another race.

Health note: this is general training information, not medical advice. If you're new to exercise, returning from injury, pregnant, or have a heart, lung or other medical condition, check with a doctor or qualified professional before you start a plan or hard workouts. Stop and get help if you feel chest pain, faintness or unusual shortness of breath.
