Your First 70.3: The Complete Race-Week Checklist

Your training has brought you this far. Now the priority is organizing the details you can control: understanding the official event rules, preparing tested gear and nutrition, and getting to your start wave on time. This guide connects those decisions to a simple timeline.

Published 4 November 2026 · Reading time approximately 8 minutes · Educational guide, not a training prescription.

Always check the actual athlete guide. Events differ in bicycle check-in, transition access, swim procedures, aid stations and cut-off times. Even events within the same race series may use different schedules. Official organizer updates override everything on this page.

7–5 days out: confirm the event details

Before worrying about a minute here or there in the race, confirm the facts that can create the biggest surprises.

Download the latest official athlete guide and look for registration, briefing and check-in times.
Confirm the exact swim, bike and run distances, including any changed course sections.
Read the event-specific cut-off rules. Some use individual chip time, while others also involve absolute course closure or intermediate checkpoints.
Find the transition zone and locate entry and exit directions. Note whether your bike must be checked in the day before.
Check the current swim safety, wetsuit, drafting and mandatory equipment rules.

A common mistake: assuming every 70.3 has identical cut-offs and check-in rules. For example, historical event athlete guides show different operational details, including transition closing times and bike check-in arrangements. Use those examples to understand what to look for — not as current rules for your race.

When these checks are complete, use the free 70.3 Readiness Check to note any remaining gaps.

4–3 days out: simplify your equipment

Now is the time to confirm rather than reinvent. Inspect the bike, tyres, brakes and equipment you know how to use. Confirm your helmet meets organizer requirements and rehearse how you will move through both transitions.

Swim kit

Check your goggles, cap rules, wetsuit eligibility and anti-chafing plan. Bring a tested spare if useful. Avoid trying a new wetsuit or goggle setup without practice.

Bike kit

Lay out shoes, helmet, glasses, nutrition, bottles, repair supplies and charged devices. Determine which items must go in organizer-issued transition bags, if applicable.

Run kit

Prepare shoes, socks, number belt and anything you normally use for comfort or weather protection. Know where your run equipment is stored.

Decision worksheet: Write down the three items that would be hardest to replace on race morning. Verify their condition and exact location now.

2 days out: rehearse your race decisions

Use estimates based on relevant training, not your best ever standalone swim, bike and run efforts. Make a conservative, baseline and faster plan with the Race Dashboard, then consider how conditions could alter those assumptions.

Prepare a race-fueling inventory based on products and quantities you have already tested. Read the actual course aid-station information so you do not assume every station stocks the same food or drinks. The Fuel Planner helps calculate supply quantities from your own assumptions; it does not prescribe what you should consume.

Write down one response to a possible problem, such as delayed parking, an equipment issue or unexpected weather. A simple contingency plan is more useful than trying to eliminate all uncertainty.

1 day out: follow the official check-in process

Review the latest event email for schedule changes. If bike racking is required, follow the assigned time slot and bag procedure. Walk the transition route if access is allowed, and make note of your numbered rack and the swim-in, bike-out, bike-in and run-out directions.

Pack your morning-clothes bag if applicable, charge electronics, and prepare your tested food and drink. Keep your registration requirements accessible without publishing personal details online.

Don't assume you can access your bike whenever you want. Some events close transition before the swim starts and have very specific bag-drop rules. Your own athlete guide determines the timeline.

Race morning: work backwards from your wave

There are several different deadlines: when to leave, when to reach the event area, when to access transition, when to move to the swim start and when your wave begins. Treating them as the same time is an easy planning error.

Confirm the current start and transition closure schedule.
Add travel time and a realistic buffer for parking, walking and queues.
Follow permitted transition access and finish essential equipment checks.
Move toward the start area in accordance with the organizer's instructions.
Stay flexible if officials announce changes, particularly concerning the swim.

Our Race Day Timeline Planner works backwards from the entered start time. The tool cannot see traffic conditions, time-zone changes or organizer access restrictions; add these from the official event information yourself.

The five-minute final review

Before leaving your accommodation, review these five questions:

Do I know the correct current start wave and event entrance?
Have I checked my registration, bike check-in and transition requirements?
Are my essential equipment and tested nutrition ready?
Have I allowed enough time for the full journey to the start area?
Do I know what to do if the organizer changes the plan?

If you answer “not yet” to any of these, that is your next practical task. A perfect checklist is not proof of fitness, medical readiness or a safe finish.
