Eddie Clark Media

The 2020 CTR Group Start will head out of Waterton Canyon, 6:AM, Sunday July 26th, 2020, all the way to Junction Creek TH for the finish. As of now the course will be unchanged from previous years. The only reason this will change is due to extreme weather, fires, etc and any changes will be relayed closer to the start. Below is the basic route description, the CT Guide book is highly recommended for first timers, or a solid review of what to expect. Navigation is the rider’s responsibility so be prepared, between maps, guidebooks, cues, and GPS, following the well marked trail isn’t too hard, but be prepared for the detours and for being sleep deprived!

Remember the famous and wise words from Eddy, “There are too many factors you have to take into account that you have no control over…The most important factor you can keep in your own hands is yourself.”  Bottom line is you can’t be too prepared for a monster like the CTR, knowing your gear and the trail can save many a heart ache while out there!
