To all Lost & Found participants, we can't wait for you to experience the 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 Raddler, Riddler or Resolute 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 100mile 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. Starting from the City Park in Portola, you will launch into the magic that is the Lost Sierra.
For racer age groups and levels see our registration page.
Our goal is to send riders off to explore the vast North Eastern Sierra, and to get out there and find the vast backcountry valleys, big mountains and spectacular lakes that are the Lost Sierra.

All categories will stage at least 15 minutes prior to start time for instructions on completing the ride.
Many will choose to ride, rather than race and take advantage of the views, the libations and the serenity.
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 Enclosure”, 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 Enclosures 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 time frame. 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 multiple aid stations evenly spaced on all routes. They’ll be stocked with fresh water, energy snacks and all the great items our generous aid station sponsors provide each year.
