The Ride

2019 SNOW ANNOUNCEMENT: Two changes to the course due to snow cover.

  1. After Aid Station #2 - the 100 and 65 mile courses continue down 24N12 to get racers out of the snow faster and the road has been plowed.
  2. After Aid Station #3 - the 100 and 65 mile courses will turn off of 24N35 onto 24N54 to avoid snow at the top of 24N35

Overall the route is roughly 3 miles shorter than the original published routes for 100 & 65, with slightly less climbing. We rerouted to snow plowed roads - which should have minimal-to-no snow on the road by race day. Expect some snow on the sides of the course and mud from snow melt. All maps, GPX and Route Sheets are updated.

To all Lost & Found participants, we can't wait for you to experience three brand new and beautiful backcountry routes deep in the Lost Sierra!

This is the Sierra so plan on running wider tires with more tread. We recommend at least 40mm wide tires for cyclocross bikes (like  WTB Nano 40mm tires), and riding a light, fast rigid mountain bike with 2.0 tires wouldn't be a bad choice either, especially if you are more comfortable on a mountain bike. There are lots of rocks and rain ruts crossing the dirt road sections in numerous spots, so when in doubt, check your speed a little. Although there are sections of gravel and almost 20% of road in the approximately 106-mile event, the non-road sections will make you savor the pavement and all the amazing views.

This year will be much more than just a "gravel grinder"; it will be a rugged and beautiful off-road adventure - Lost Sierra style - so plan accordingly. The proposed course is much smoother than in past years, as it uses higher-quality and maintained Forest Service and County roads.

There will be a dedicated course sweep for all course lengths. 

The Ride will be held rain, shine, sleet or snow. In the event of extreme weather or natural disaster, the ride may be shortened, postponed or canceled without refund.


During a “Rolling Closure”, vehicle traffic will be stopped and controlled by course officials and/or law enforcement to ensure rider safety and to keep the peloton moving swiftly. Once the peloton has passed through, the intersection will re-open to vehicle traffic. Rolling Closures are estimated to take no more than 10 minutes at each intersection. Riders riding behind the peloton must obey all rules of the road, as there will be no Rolling Closures in place.



If at anytime an STBS staff member, or a member of the emergency response team, determines a rider is physically unable to complete the event within the allotted timeframe. You must accept a ride back to the emergency response center at the Portola City Park/Finish area.

Course officials reserve the right to remove and “DNF” any rider from the event that is deemed incapable of safely finishing the course for any reason.

If you do not make the cut-off time or are unable for any reason to finish, please DO NOT go through the finish line as it will foul-up our results!


There will be five aid stations, located less than 25 miles apart throughout route.
They’ll be stocked with fresh water and energy snacks.
Garbage cans will be placed at aid stations to dispose of any trash.
