Five things it does
01You race while you rideA live +/- against the holder's actual splits, not a verdict after you get home.MORE
Hit a stretch you're chasing and the ghost of the current holder is beside you, reconstructed from their real splits. Went out too hot? You see it. Crowns live on rolling windows, today, this week, this month, this year, all-time, so there is almost always a bar within reach.
02Every road is named and timed1,262 stretches in the Triangle. 1,232 with nobody on the board.MORE
Segments are built from the road graph and named from the map: Goose Creek Run, Massey Chapel Straight, I-40 Bridge. Nobody has to draw them. See who holds what this week →
03Outside and inside are one rideRide a road. Ride it again on your trainer at its real grades.MORE
Finish a ride and that road exists indoors. Rainy week? A connected world of real places, the Triangle's greenways, the Outer Banks, the Alps, with live riders to draft. Every kilometre counts once, wherever you rode it. The world is ugly and I need help with it →
04It watches the road with youWarned before a bad stretch. Free, forever, on every plan.MORE
A voice speaks up before a stretch with a history of serious crashes and before hazards other riders flagged. Go down and don't get up, and the people you chose get your location. One tap sends a beacon; one link shares your ride live.
05Bike, run, swim, one effortBrick and triathlon with the phone and the watch handing off.MORE
Stop the bike, start the run, and it's one connected effort, not two files nobody links. Recording jumps between phone and watch. Still the thing I've rewritten the most.
