Registration rules vary by event and year. Use the official website and registration page links above, and confirm any lottery windows, qualification rules, and transfer policies before you plan travel.
Pick a plan length that matches your base and injury history (often 16–24 weeks), then train backward from race day and include a taper.
Start conservatively, settle into rhythm, and protect the final 10K. Use effort cues if conditions change.
Race-specific long runs, fueling practice, and dialing in pacing cues. Avoid late ‘hero’ sessions that spike injury risk.
Use the pace calculator to explore scenarios, then anchor training by effort and recovery. Your goal pace should be earned in training, not guessed on race week.
Practice your fueling schedule in long runs and use a conservative default early (carbs, fluids, and sodium). Adjust for heat and your gut tolerance.
Treat heat as a pacing variable. Start more conservatively, fuel and hydrate earlier, and practice one or two long runs with heat adjustments so your race-day plan isn’t improvised.
Protect sleep and keep the plan simple: arrive with a buffer, keep walking low, rehearse transport to the start, and avoid adding new workouts or new foods late.
Start practicing early — not in the final week. Rehearse the same gel/fluid schedule during long runs at steady effort so your gut tolerates it under load.
