All courses are run on a mix of single track, horse trail, and gravel road. The 100K distance will run the 50K loop twice.
Every 100K/50K runner will be expected to climb the fire tower (or vertigo option) on their first loop. 100K participants can optionally climb the fire tower (or vertigo option) on their second loop to be officially recognized as a “Fire Tower Overachiever“
Vertigo Option: All participants have the option of using our vertigo option stairs instead of climbing the tower. You simply climb the first flight of stairs 8 times in a row to simulate getting to the top.
Please be respectful of other participants and other park visitors and do not crowd the fire tower. If you need to pause and let park visitors get past you, give them the right of way.

Pacers and Crew
Due to limited parking and access, crew is only allowed for 100K participants and only at the Overlook Aid station and Start/Finish. Crew may not go to Gate 31 or Fire Tower. If your crew would like to visit the Fire Tower as a park visitor they are certainly welcome, but they cannot crew you at this station.
Pacers are only allowed for the 100K after you have completed your first 50K loop. You can pick up a pacer at Start/Finish or at the Overlook Aid station. You may swap pacers at the Overlook Aid station either time you’re passing through the station.
