Boulder Rez Half Marathon, 10K & 5K

We are excited to be producing the 1st Annual Boulder Rez Half in 2015. 

The Boulder Rez Half will take you around the lake on some awesome single tracks, a packed-dirt trail on the dam, and paved Reservoir Roads. The 10K and 5K will be an out-and-back run on the dam while the ½ marathon athletes will complete 2 loops around the lake. This is a highly requested course by local Boulder athletes!

Start Time: 7:30am

This out & back course is flat, fast & beautiful as you run across the Boulder Reservoir dam.  There will be 5 opportunities to fuel up at or near each mile marker, preparing you for that slight downhill sprint to the finish!  Olympic athletes will need to complete 2 laps.
