About this extension

Plan your Strava routes around the climbs you want to ride. Cols Atlas brings 5,000+ cycling climbs directly into Strava's route builder, so you can discover cols, explore their profiles, and add them to your route as waypoints.

See exactly where climbs sit along your route and elevation profile, with difficulty ratings from HC to Cat 3. Explore 5,000+ cols and 9,300+ climb sides across 20 countries.

Works entirely locally — no account, no external servers, and no data collection.

Developer comments

Cols Atlas does not require an account and does not collect user data.

The extension runs on Strava route and map pages and uses a bundled climb dataset. No external backend is used for the extension's core functionality.

Climb details may include links to CyclingCols for additional information when selected by the user.
