We will be camping on Friday prior to the event. On Friday evening we will have a navigation skills seminar as a tune-up for the races on Saturday. These will run from 5 pm until 7pm on Friday. They will be led by experienced adventure racers who can share years of race experience and stories. On Saturday evening after the events we will have a good evening to share stories if you care to join us. Saturday evening camping will also be available.

On Saturday, teams will check in and stage their equipment (bikes, boats) as directed near the start area. Teams must be checked in, have equipment staged and be ready to attend the pre-race briefing at 7:30am. Route instructions and maps will be distributed during the pre-race briefing. Teams will have a few minutes to review the route and maps prior to the start. Teams may remain near the start area to plot routes or adjust equipment once the start has occurred. Part of adventure racing is to quickly prepare for any discipline and quickly plan routes and strategies, or at least the beginnings of them. Continuing to plot and strategize as you move is another adventure race skill.


The event will be based at the Tuttletown Recreation Area on Lake Melones. Follow Highway 49 North from Sonora about 8 miles and watch for the left turn to Tuttletown. The event will be at the Eagle Point day use area. Camping and activities on Friday evening will be at the Fiddleneck group campground. Camping on Saturday will also be at the Fiddleneck group campground. Please let us know if you will be camping at the group area on Friday and/or Saturday night. You may also reserve private campsites through.. Camping

If you make a private reservation, make sure you reserve in the Tuttletown Rec area and not the Glory Hole area which will be much less convenient.

New Melones is under Bureau of Reclamation management. Entry is $8 dollars per vehicle unless camping. National Park passes are accepted.
