Ride it at home

Pair a smart trainer and ride this route from home. The resistance follows the climbs, the dot moves at your speed, and the park's warnings pop up as you reach them.

Difficulty sets how steep the climbs feel on the trainer: 100% is the real grade. Your speed on the map always uses the real grade and your weight.

Route traced on OpenStreetMap data (© OpenStreetMap contributors, ODbL); elevation from Mapzen/AWS Terrain Tiles. Grades are worked out over about 200 m from public elevation data and can be off by a percent or two, more on tight switchbacks. Check the Rocky Mountain guide and the park's own page for current rules and closures before you ride.
