Entry point
The course is cut into climbs and descents, each one a gradient: steepness × length. The challenge is to run them all on your own trails — flat ground is not scored. Shown here complete: this is the full set to collect.

Every synced training is scanned for climbs and descents that match the course, steepness × length, uphill and downhill counted separately.
Each matching effort inks its segment onto the drawing. What is closed stays closed, there is no fail state.
Terrain you haven't run yet stays hatched on the drawing. Trail Finder pulls the nearest real segments that would close it, ranked by distance from your door.
Levels are nested, each one contains the previous.
Run every gradient of the course at least once.
Cover the full course segment by segment. Two identical walls on course means two walls run.
The whole course plus the long linkups, several climbs in a row, run in one unbroken push.
There is no fail state. Levels are nested, so you finish at whatever level you reach. A closed segment stays closed.
