Triathlon race week prep is a balancing act: taper enough to arrive fresh, but stay sharp enough to race hard. This guide covers the practical side — what to do, what to skip, and how to make the final week work for your body rather than against it.
Race week prep is not about last-minute fitness gains — it is about risk reduction. Every decision you make from Sunday to Saturday should ask one question: does this make me more likely to have a clean race? Skipping a 90-minute bike ride you feel you need probably does. Trying a new gel brand on Thursday definitely does not.
The athletes who race best in race week are the ones who have a plan and stick to it. Improvisation is the enemy of a confident start line.
For most athletes, race week volume is 40–60% of a standard training week. If you are racing a full Ironman, you might do one moderate brick session on Monday, two short activation swims, and one easy 20-minute run. For a 70.3 or Olympic, even less.
Intensity can be kept slightly higher than volume — a few short efforts at race pace during activation sessions keeps the neuromuscular system primed without generating fatigue. But stop well short of anything that leaves you feeling worked the next day.
Monday: last meaningful session (moderate brick or long swim).
Tuesday–Wednesday: activation only — short, easy efforts.
Thursday: optional 20-minute jog or swim.
Friday–Saturday: rest or 10-minute shake-out maximum.
Race week nutrition has two jobs: top up glycogen stores and avoid any GI disruption. Both goals point in the same direction — eat familiar, digestible carbohydrates and avoid introducing anything new to your gut.
From Wednesday onwards, shift your plate composition toward carbs. Rice, pasta, bread, and potatoes are reliable. Reduce high-fibre vegetables, cut alcohol entirely, and drink consistently throughout the day so you arrive at race morning already well hydrated.
Increase carb proportion at each meal from Wednesday.
Avoid raw vegetables, beans, and high-fibre foods from Thursday.
Nothing new on race day — or in the three days before it.
Sip electrolytes alongside water, especially in warm climates.
Use Race Preprr's nutrition planner to map out your day-before meal plan and race-day cues — so you are not making decisions about when to eat your first gel while standing in the transition queue.
Sleep is the most underrated race week prep tool. Research consistently shows that one or two nights of poor sleep immediately before a race has minimal effect on performance — but the preceding five nights matter enormously. Prioritise sleep from Sunday onwards, not just Friday night.
Reduce screen time after 21:00, keep the room cool and dark, and treat any pre-race anxiety as normal. The adrenaline you feel at 3:00 am is not ruining your race — it is preparation.
Aim for 8 hours in bed each night from Sunday.
Keep your room cool (16–18°C / 60–65°F is ideal).
Do not lie awake worrying about lying awake — it is normal.
Avoid caffeine after 14:00 from Wednesday onwards.
If racing away from home, add a travel buffer of at least 24 hours before race day. Arriving on Friday for a Sunday race is manageable but tight. Wednesday or Thursday arrival gives you time to register, attend the briefing, and recon the venue without rushing.
Check airline or train policies for bike transport early — bike boxes have size limits, and last-minute bookings are expensive. If renting a race wheel or bike at destination, confirm availability months in advance.
Book bike transport with your travel booking, not as an afterthought.
Carry nutrition, race kit, and essential items in hand luggage.
Identify the nearest bike shop to race venue in case of equipment issues.
Check check-in bag weight — race equipment adds up quickly.
Race week is mentally taxing even for experienced athletes. The combination of reduced training, heightened awareness of every bodily sensation, and logistical pressure creates a low-level anxiety that can derail preparation if you let it.
Having a written plan removes a significant proportion of that cognitive load. When every decision — what to eat, when to sleep, what is in each bag — is already made and written down, your brain has less to worry about. That is the practical case for race week planning beyond the logistics.
Write down your race day pacing targets and nutrition plan.
Visualise the swim start, first km of the bike, and run out of T2.
Have a plan B for common problems (dropped nutrition, flat tyre).
Trust your training — fitness does not disappear in one week.
Not all gear checks are equal. The ones that matter most are the ones that can cause a DNF or a significant time loss if they fail. Tyre pressure, helmet certification, timing chip fit, and race number attachment are the critical checks. Everything else is secondary.
Go through your bags systematically, not randomly. T1 bag first: helmet, sunglasses, gloves, bike shoes. T2 bag: run shoes, visor or hat, race belt with number, any additional nutrition. Special needs: whatever your race nutrition strategy requires.
Tyres inflated to correct pressure (check race morning, not just Thursday).
Helmet certified and straps undamaged.
Timing chip fits correctly and is on the correct ankle.
Race number attached to belt or pinned to race kit.
Race Preprr's bag packing tool lets you assign every item to T1, T2, or special needs and mark each one as packed — print the list and run through it on Thursday.
