RACE PACKRace Pack · web app for runners
Your race-day drinking and fuelling plan, built from your own sweat data
The free planner gives you the guidelines. The Race Pack learns from your own runs, then turns the race-day forecast into how much to drink at each station.
What's in it
- Sweat log and model. Weigh yourself before and after your runs. The pack works out your sweat rate, and from your runs in different weather learns how temperature, humidity, pace and run length change it.
- Race-day drinking plan. Pick your race, and the forecast for race day becomes millilitres at every drink station, with the range of finishing weights to expect.
- Gels and pace band. Mix the gels you use; the pack spaces them to hit your carb target and prints them on a pace band next to the drink stations.
- Carb loading. A day-by-day plan from the food labels you actually eat.
- Practice plan and race-week checklist. Rehearse the plan on long runs, then tick off race week.
- Sweat sodium. From a sweat test if you've had one, or an estimate from three questions.
Every figure cites its source, as on the rest of the site. Already keep a sweat log in a spreadsheet? Import it as a CSV.
