FreeTrain. Structured training that costs nothing

The parts you'd otherwise pay a subscription for.

No feature is held back, metered, or reserved for a paid tier. There isn't one.

ERG mode control: Holds your trainer at each interval's target power over Bluetooth FTMS, so the resistance follows the workout instead of your legs.
Plans that adapt: Tell the coach your goal and your week, and it writes a periodized plan of any length. It then reshapes upcoming sessions around what you actually completed and how hard it felt.
Training load, done properly: Normalized Power, Intensity Factor and TSS computed the way coaches expect, plus weekly load, adherence and time-in-zone.
One calendar, four sports: Rides, runs, swims and lifts share a single calendar, so you can see a heavy Saturday coming before you schedule anything against it.
Workout builder: Build intervals against a live power profile, then save and reuse them anywhere in your plan.
Strava sync: Completed rides upload with full power data. Activities you record elsewhere come back in and count toward your plan.

Each sport is planned on the terms it's actually measured in, and all of it lands on the same calendar.

ERG-controlled interval sessions built around your FTP.

Mileage plans that watch your weekly ramp rate, road or trail.
