The Rock Creek Ramble is a team adventure you won't want to miss! Plan and follow a route on foot to as many of the 50 checkpoints marked on the map as you can in your chosen time limit. Go for 4 hours, 7 hours, or the full 10 hours. A team on the course!

Participate solo in the 4-hour or 7-hour events or go in a team of 2-5 in the 10-hour. We are offering 4-hour participants a choice of start times: 7:30 a.m. or 12:30 p.m.

There will be a mix of checkpoint difficulties, with most checkpoints requiring some off-trail, cross-country navigation. The open nature of the terrain makes the area more forgiving to less experienced cross-country navigators than a forested area, Rock Creek flowing through the grassy valley with basalt cliffs in the background however novices would find this event quite challenging, so some prior navigation experience is recommended.
