Your race day, minute by minute

Tokyo Marathon · Sunday, March 7, 2027 · gun at 9:10 AM local. Built for a 4:30:00 marathon — change it below and every clock time updates.

The night before

  1. 6:00 PMDinner

    Carbs you've practiced with in training — nothing new, nothing heavy, done by 8. Hydrate normally; don't tank up.

  2. 8:30 PMLay everything out

    Bib pinned, chip on, kit + throwaway layer, breakfast on the counter, phone charging. Race morning should require zero decisions.

  3. 9:30 PMLights out

    You'll sleep badly — everyone does. The night that matters was two nights ago, so don't panic-watch the ceiling.

Race morning

  1. 6:10 AMWake up

    Three hours before the gun. Eat your practiced breakfast within 15 minutes — it needs time to digest.

  2. 7:25 AMLeave for the start

    Big-race logistics eat time: road closures, security lines, crowds. Staying within walking distance turns this into a stroll.

  3. 7:55 AMArrive: bag check, then porta-potty line

    Get in the porta-potty line immediately — it's always longer than it looks, and you'll want it twice.

  4. 8:35 AMEnter your corral

    Corrals at big races close early and strictly — being outside when they shut means starting waves back.

  5. 9:10 AMGun

    Goal: 4:30:00. The first miles will feel absurdly easy. That's the plan working — bank calm, not time.

On the course

Clock times at each split for a 4:30:00 finish — send these to your people so they know where to stand.

The finish

On goal pace, you cross at 1:40 PM. Realistic arrival window: 1:32 PM 1:59 PM — tell your people the late end, then beat it.

Agree on a post-finish meeting spot now (most races use lettered signs in the family reunion area) — phones are useless in a finish-line crowd.

Send it to whoever's coming to watch — it opens straight to this timeline with the split clocks.

Where to stay

Point-to-point course: stay near the finish, not the start — you'll be glad at mile 26, and shuttles run to the start. Hotels near the Tokyo Marathon start selling out 8–10 months ahead with race-weekend minimum stays — book refundable, book early.
