Calarat Challenge 10Kish

Begins in:
Lyons, CO, United States
Boulder, CO
This 10Kish (trail racing isn't exact) course run in conjunction with the half marathon race, is a bit tamer than its longer companion. Not that it will be walk in the park. Run on a mix of dirt roads and runnable single track, the race starts with short downhill before a stout climb of 300 feet in the first mile. The payoff is the cruising downhill in miles 4 and 5, before a climb back to the finish at the Cal-Wood Lodge. For those looking for less technical trails and less vertical climbing, but still want beautiful scenery and a challenging course, this race is for you. These trails are all on private property and only accessible to public on race day.
