The race formerly known as the "East-West" trail race, has quickly become a runner favorite among Endurance Race Series front range events. The newly designed courses stay true to form, as they will keep the Heart Rate pumping while offering some of the best views in the front range.
To help keep the essence of this race, but allow the ERS to cut back on road crossing traffic, the newly named Mountain Ridge Half Marathon and 10K will start and finish once again from Mountain Ridge Middle School, and be entirely located within the community of Highlands Ranch, eliminating the East-West trail use all together.
The new courses offer 100% dirt trail and single track courses , featuring manageable elevation gains.
