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.

Three 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.

gain
128

What you earned. Effort, scored — from your ride data, not your follower count.

gnar
7.2

What the trail was. Motion sensors read the rock gardens, roots, and chop, so the score stays honest when the trail gets ugly.

clean
0 dabs

How tidy you rode it. Feet stay on the pegs or the pedals — dabs count, and clean means 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.
