This is NOT your normal "Run in the park". This course was developed to give the experience trail runner something to get excited about and the novice runner a great sense of accomplishment. The course has everything that a true trail race should have. There are open grass fields, fast ridge line single tracks, technical rocky/rooty up hills, minor stream crossings, flat straightaway's ,fast tricky down hills , and < 1% is run on concrete. Plus, a water stop at the half way point for the 10k and 3 water stops for the 21k. I guess I shouldn't mention that there is 1000ft of elevation gainin the 10k and close to 2,000 for the 21K...as a trail runner, you should LOVE to climb!!
