The Lost & Found course features a perfect blend of pavement, dirt road, gravel road and historic railroad grade. Racers must choose their bike wisely as you're not in Kansas, this is the high Sierra.
The longest route is 96 miles with 7,688' of elevation gain and is 70% dirt. Also available are two shorter and still challenging course options; the 64 mile, with 4,928' gain, and the 40 mile, with 2,503' gain.
All routes start in Portola at the City Park and lead into the surrounding mountains hrough some of the most beautiful and vast alpine valleys California has to offer.
Participants can choose to race or simply ride the route and take advantage of the quality aid stations. Racers and riders from around the world will be invited to lose themselves and find this two-wheeled paradise.
Saturday ride and post event fun in Portola with food, beer, live music, and dancing - the way we like to do it! The festival also celebrates custom frame builders with the Builders For Builders tent, showcasing beautifully crafted frames handmade by the top U.S. fabricators. Many of the builders also take part in Lost & Found on Saturday! Come join us for a great weekend in the Lost Sierra.
