30 courses ranked by total climbing
The 70.3 courses with the least climbing in the directory, by total elevation gain across bike and run. Climbing is the single biggest driver of the automatic difficulty rating, together with water temperature and how finishers compare with the average for the distance. Use the flattest courses as a reference when you are chasing a personal best; the Race Lab converts climbing into time once you set your own bike and run paces.
