This event is not a joke. It is a true test of your fitness in every sense. Lake Sonoma is a very rugged place with the terrain to match. Isolation is a regular condition out there, so be safe and try to silence the nagging voices in your head. In short: if you’re considering entering this event, you should be training for it.
