The climb to the radio tower was added as part of the Epic KOM expansion in March 2016, and it quickly became Zwift-famous (Zwinfamous?) for its super-steep grade that is made even more challenging by a slow-rolling ice/snow road surface.

It wasn’t until June of 2024 that this became an official KOM segment. The “Power to the Tower” route became the first to end atop the Radio Tower KOM, but we’ll surely see others in the future.

The Radio Tower KOM’s average gradient of 12.8% puts it head and shoulders above any other climb in Zwift in terms of pure steepness. The next steepest climb? Richmond’s 23rd Street KOM at 9.3%, and the Radio Tower KOM is more than 4x longer!
