Race-time predictor
One recent race gives your equivalent times at every distance, and an honest read on whether your goal is on for the weeks you've got.
Open the toolPace & zone calculator
Your easy, long, marathon, threshold and interval paces, each with the heart rate to match, so your watch and your legs are training the same effort.
Open the toolMarathon pacing & splits
Your goal time turned into the clock at every marker, even or a controlled negative split, so race day is a plan, not a guess.
Open the toolBuild & taper
A safe week-by-week climb to your peak with cutback weeks built in, then the three-week taper that brings you to the line fresh rather than flat.
Open the toolFuelling & hydration
Your race-day carbs, fluid and sodium per hour, turned into how many gels (or which bottle) it actually takes, plus carb-loading and an aid-station plan. So race day is rehearsed, not a gamble.
Open the toolHeat & humidity pace adjuster
Enter the forecast temperature and humidity and see how much they'll cost you: an adjusted goal pace, plus a sense of the heat risk.
Open the toolRace-day Mind Plan
Build your own mental game plan for race day: cue words for each phase, an if-then plan for the moment it gets hard, and a short rehearsal to run through in the final week. Free, no account.
