Checklist

Make sure it's still valid — you'll also need it as ID at bib pickup

Check if your nationality needs a visa or travel authorization (ESTA etc.) and how long it takes

Print or save it — you may be asked at immigration or bib pickup

Required for some races (France, Italy…) — check the required documents in the race notice

Cover injuries, delays and lost baggage

Keep them in your carry-on, never checked — you still race even if your bag is late

Mind cabin liquid rules — on-course brands may differ, bring what you trained with

Bib pins · watch charger · Vaseline · a throwaway layer for the start

Some places are cash-only — carry small cash plus a card that works abroad

Check plug type and voltage, and pack a universal adapter

Check pickup dates, closing times and required ID — many races don't allow race-day pickup

Check first trains and shuttles — public transit may not run that early

Check bag drop deadlines, clear-bag policy and wave start times
