A dashboard for runners, cyclists, swimmers, triathletes and Hyrox athletes. It turns lab-tested VO₂ max, thresholds, metabolic rate and body composition into your training zones and fueling targets.
Default heart-rate zones come from a formula like 220 minus your age. It can be wrong by a lot, and every session gets judged against it.
A plan built on a guessed threshold and a guessed calorie target is a guess on top of a guess.
A lab test is only useful if it changes what you do next week. Your numbers should live where you train.
Heart-rate zones set from your ventilatory and lactate thresholds, with pace, power or swim targets for your sport.
Daily calorie baseline from your measured RMR, protein from lean mass, and carbs per hour for long sessions.
Lab measured, field tested or estimated. You always know which numbers to rely on and which are still guesses.
Retest and see what moved, for example your VO₂ max change since the last test.
Run, bike, swim, triathlon and Hyrox, each with the right units and targets.
See which tests you have done, which are still missing, and what each one would unlock.

It is a training tool, not medical advice. It tells you when a number is soft.
Switch sports, change the test source and see how the numbers respond.
Sign up in a minute. It works straight away and marks anything untested as "Not tested" instead of inventing numbers.
VO₂ max and thresholds, lactate, resting metabolic rate and body composition. Each one fills in a part of your dashboard.
Your results appear in your dashboard. Retest every 8 to 12 weeks to see your progress.
Your zones and fueling are only as good as the data behind them. Box runs the tests that replace the guesses.
Sets your zones and shows how you burn fat and carbs.
Confirms your Zone 2 ceiling and hard-effort threshold.
Your real daily calorie baseline.
Lean mass and body fat, for protein and progress.
Your own dashboard, your test results, zones and fueling, with retest tracking. Tests are booked separately with Box.
Free to start.
No. You can start without one, and anything untested is clearly marked. A test replaces the estimates with measured numbers.
Your test results appear in your dashboard straight away. Connecting Garmin, Coros or Strava for your daily training data is the next thing we are building.
Your results are stored securely and used only to run your dashboard. You can download everything or delete your account at any time from inside the dashboard. We never sell your data. Read the privacy notice.
No. It is a training tool. Sharp pain, illness or anything medical should go to a professional. Read the terms.
