Course & elevation

Tokyo is flat and fast, with only gentle grade changes through road underpasses and a couple of out-and-back sections. Pristine organization and orderly crowds make pacing easy.

Key moments

  • Mile 1–3A net downhill start out of Shinjuku — don’t bank the free speed.
  • Mile 8–16Out-and-back sections — useful to spot the leaders and your pace.
  • Mile 24–26.2Flat run-in toward the finish near Tokyo Station.

Pacing strategy

An even effort suits the flat profile. The downhill start invites a too-fast first 5K — rein it in and you’ll have a strong, controlled second half.
