Entry point
A challenge breaks a real race into gradients, climb and descent steepness and length, and asks you to run each one. Your trails, your pace, a window.
No challenges are open right now. Come back before the next season.
Levels are nested, each one contains the previous.
Connect Strava once. Your runs sync on their own, and every climb and descent in them is measured for you.
Link Strava once and your runs download on their own — every climb and descent in them is measured automatically. Joining, you either start clean or credit your last weeks.
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.
A steep 400 m wall and a gentle 4 km grind are different gradients, the drawing needs each of them. Uphill and downhill are counted separately; flat stretches are not scored at all. A longer effort of the same steepness closes a shorter requirement; a shorter one never closes a longer.
When a gradient is nowhere on your usual routes, Trail Finder searches real segments around you, confirmed by finished efforts or mapped from the trail network.
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.
