Pace calculator
Distance + target time → pace per km, the exact treadmill speed to set, km splits, and equivalent race times at other distances.
Open →Free running tools
Browser-based, no signup, nothing uploaded. The same math that powers the gym2x training platform.
GPX → treadmill plan
Upload any route's GPX file and get a km-by-km treadmill program — incline, speed and time — to simulate the real course indoors.
Open →Timer & countdowns
Workout timers with huge digits, beeps and screen wake-lock — presets from 1 to 60 minutes, a Tabata/circuit interval timer, and countdowns to the end of the day, season, year, and your race day.
