The Lost Sierra Triple Crown – A Premier Knobby Tire Challenge

For riders seeking the ultimate challenge of both fitness and bike handling skills, the Sierra Buttes Trail Stewardship presents the three-event, Lost Sierra Triple Crown.

Lost Sierra Triple Crown

Consisting of the:

Lost & Found 100-mile Gravel Grinder - June 3rd

The Lost & Found course features a perfect blend of pavement, dirt road, gravel road and historic railroad grade. Racers must choose their weapon wisely (road bike, cross bike or mountain bike). The route is 100 miles with 7,000' of elevation gain and is 80% dirt.

Downieville Classic Cross-Country - August 5th

The Downieville Classic cross country race is one of the last remaining point-to-point bicycle races in the United States. The 29 mile course follows a rugged "Gold Rush" era route that departs the mountain town of Sierra City (elevation 4,100'), climbs to the crest of the Sierra Nevada (elevation 7,100'), and then plunges 5,200 vertical feet into downtown Downieville.

Grinduro - October 7th

Grinduro is just what the name suggests: Gravel Road Race + Mountain Bike-Style Enduro = one long loop of pavement and dirt, where finishing times aren’t based on overall loop time, but four timed segments (each roughly five-to-seven minutes). The course is a serious affair (7,500-feet of climbing in 60 miles) but the Grinduro isn’t meant to be a sufferfest.

The Lost Sierra Triple Crown will promise to be a fun and challenging endeavor for all participants.

The Lost Sierra Triple Crown will be based on the same points system used in the Downieville Classic All-Mountain World Championships, and will be applied to placing based on the three aforementioned events across 13 lucky categories.

To be eligible, riders must register for the Lost & Found 100-mile event, the Downieville Classic Cross-Country (All-Mountain participants are also eligible) and the Grinduro – a unique event combining a gravel grinder with an enduro.

Triple Crown winners will be announced at Grinduro on October 7th.

Riders can use any bike they wish for the three different events; the same bike is not required. For those not familiar with the three events, a cyclocross bike with disc brakes and tubeless tires has been very successful at the Lost & Found and Grinduro, while a capable hardtail or lightweight full-suspension bike with durable tires works best for Downieville.

Riders participating in the Lost Sierra Triple Crown must indicate during registration of each event they wish to take part by clicking a box during the registration process. Racing age will be determined based on age as of December 31, 2017. Registration for the first event in the series, the Lost & Found, registration will open on Sunday, March 5 at 8:00pm Pacific. With attendance doubling between its first and second years, the third-annual Lost & Found at Lake Davis, Calif. on June 3rd will likely double in attendance again for 2017, so early registration is recommended.

Registration for the Downieville Classic opens on Sunday April 2nd at 8:00pm and Grinduro opens on Sunday April 23rd at 8:00pm. Both events are expected to sell out quickly, so participants are encouraged to mark their calendars and register on the opening dates. There is no registration offered for all three Triple Crown events at one time, participants must register individually for each event.

“After a few friends took on the challenge of doing all three events last year, we thought it would be really fun to make the Lost Sierra Triple Crown an official event,” said Greg Williams, Executive Director, SBTS. “We believe the Triple Crown will be the ultimate test of a true backcountry rider, because if you’ve ever ridden in the Lost Sierra or done one of our events, you know that there’s no hiding; you have to be super fit and extremely skilled to prevail.”
