ride together, race yourself.
GripTrails is a performance instrument for off-road riding — mountain bike and moto. It measures the trail, measures the run, and remembers both, so you can race the only rider who matters: you, last time.
Join the betaFour numbers, no fluff
Strava counts your miles. Trailforks knows the map. Neither can tell you whether today's run through the rock garden was actually better than October's. GripTrails can.
What you earned. Effort stacks mile by mile — the number only climbs while you work.
What the trail was. Motion sensors read every hit — the spikes are rock gardens, roots, and chop. Pure trail, never the rider.
How smooth the line was. The same section ridden twice: fought (gray) and flowed (moss). One number for the whole run.
What the run took back. Every flow-break counts against you, weighted by how bad — a dab costs least, a crash costs most. Loss zero: you rode it clean.
Same trail, over the years
Every run lands in that trail's ledger — across seasons, bikes, and setups. Today's trace rides over last time's, so improvement is something you can see, not something you feel like happened.
Group rides stay group rides. Your buddies are on the trail with you; the racing happens against yourself.
