The Mother of all Singletrack

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.

About the Route

The long route is 34.5 challenging miles of steep terrain with whippy turns, and foot-out off-camber descents. It's for the rowdiest of mountain bikers. The climbs are short, steep, and come at you constantly. The descents are of a similar character. There are very few long climbs to set into and just as few long descents to use to get around all those people who passed you on the climbs. Expect to pedal, and if you are racing in the singlespeed category, opt for an easier gear ratio.

The medium route includes mos of the challenging stuff but excludes the first offroad section and instead continues for 2.5 miles on pavement until re-joining with the long route. It also takes a shortcut between the Liberty Glenn aid station and the Wulfow Shortcut aid station meaning that for those riding the "Feral Pig". Note: The "Wulfow Shortcut" aid station will only be in place for long-course riders. So if you need something on the medium route, get it at Liberty Glenn!

The short course only stops at the Liberty Glenn station and then turns off on to additional single track not laid out in the profile below. Remember, the short-course is a non-competitive (not timed) route.
