About Grimpa
Grimpa draws real roads as pixel-art worlds built from map and satellite data, and sends each gradient to a Bluetooth FTMS smart trainer. It runs in Chrome or Edge with no install. Structured workouts run in ERG on any road, and friends can ride together or join scheduled group rides, with no races or leaderboards. Riding is free; extra GPX routes and map packs are paid.

A training plan made for you
Tell Grimpa your goal, your level and the days you can ride, and it builds a plan around you, every session set to your own watts. Every ride counts, indoors or outside with Garmin or Wahoo, and when you miss a day or feel tired, the rest of the week adapts. Try it - Grimpa: Two volumes for the ride's soundRide settings now have separate volume sliders for road and crowd, and for beeps
- Grimpa: Bring your friends to your map pack and 2 more
Bring your friends to your map pack
A group ride you set on a map pack's route is open to everyone who joins it, pack or not. Your friends ride the Pyrenees with you for free; on their own, the route stays the pack's. Try it
Your place on the leaderboard as you ride
On every segment you now see the place you're on pace for on the leaderboard of the last 90 days, and how far you are from the place above. Before the start the fastest time waits under your ghost's, and at the line the stone says by how much you beat it or missed.
Two volumes for the ride's sound
The ride's settings now have one slider for the road and the crowd and another for the beeps, so a workout's countdown comes through over your music while the wind of a descent stays in the background. The beeps are louder than before and the road a little quieter. - Grimpa: Three new routes: Berlin, the Rhine and London
Three new routes: Berlin, the Rhine and London
Ride Berlin from the Grunewald's lakes to a race-day finale past the Olympiastadion and the Funkturm, a loop of the Rhine gorge from Bacharach, across the river and back on two ferries and under the Loreley, and laps of Richmond Park among the deer. All three are free, short and mostly flat, and each has something new to earn: tri-spoke wheels, a compact aero helmet and a jersey the colours of a sunrise.
