The race-day principle: decisions should already be made

Race day is for execution, not improvisation. If something is new, it’s a risk.

3–4 hours before start

  • Eat a breakfast you’ve practiced.

  • Sip fluids normally; avoid “panic chugging.”

60–90 minutes before

  • Arrive early enough to remove stress.

  • Final bathroom + kit check.

10–20 minutes before

  • Short warm-up (jog + a few strides) if it helps you feel smooth.

  • Start line cue: “too easy is correct.”

During the race

  • Start fueling early and stick to a repeatable schedule.

  • If it’s hot or hilly, pace by effort and let splits drift.

Training guardrails

  • Keep easy runs truly easy so workouts stay high quality.
  • Progress one variable at a time (volume first, then intensity).
  • Use cutback weeks every 3–4 weeks to absorb training.
  • If pain changes your gait, scale back and get assessed.
