Visual intervals · import .zwo and .fit · AI drafting
A cycling workout builder that moves as fast as the session idea in your head.
Shape intervals visually, reuse existing workout files, and get from idea to ready-to-ride session. Explore the builder without an account; sign in when you want to save and sync.


Build
Intervals on a timeline.
Add blocks, repeat groups, warmups, recoveries, and cooldowns while the workout graph updates as you build. Generate a starting structure from a plain-language prompt when it helps, then edit the intervals before saving.
- No hidden structure when you just want intervals on a timeline.
- Ride-ready, not export-only.
- See whether the workout looks right before any admin.


Import
Start from a file you already trust.
Bring in ZWO or FIT workout files so you can reuse sessions instead of rebuilding every interval by hand. Import one workout you already know, tweak the structure, check the graph, and decide whether the editing feels cleaner than what you use today.
- Self-coached riders and coaches building sessions repeatedly.
- Athletes turning workouts from notes into intervals.
- Riders with ZWO or FIT files they want to edit.
