Sierra 7500 History

History of the Original “Sierra 7500”:

  • The original Plumline Sierra 7500 was a pioneering endurance mountain bike race in Bishop, CA.  It was held only twice – early July in 1985 and late June in 1986.  In 1985, Roy Rivers edged out Joe Murray by a wheel length in a sprint finish for the victory.  The race was extremely well-received, and many more pros showed up for it the following year.  The 7500’s legendary status is largely due to Cindy Whitehead’s awe-inspiring win on June 22, 1986.  She snapped her seat off only a mile into the race.

    By the way, it’s a 50 mile race with 7,500′ of climbing through rugged terrain reaching elevations over 11,000′.  At the time, it was considered the most brutal of all mountain bike races.  Anyway, Cindy rode 49 miles standing up with no saddle.  After swapping the lead back and forth, she eventually beat Jacquie Phelan (pretty much unbeatable at that time), and it has gone down as one of the best efforts in the history of mountain bike racing. (Read Cindy’s account of the race in the Mountain Bike Hall of Fame).  Mike Jordan won the male category in 1986.  Official results weren’t recorded in the Norba News, but here is a partial list of Sierra 7500 race results compiled from different magazine and newspaper archives.

  • Don Douglass (co-founder of IMBA) was the race creator/promoter/director.   (See Don’s profile in the Mountain Bike Hall of Fame).  He recently dug through the garage and located the original NORBA course maps and mailed them to us.  *Side note – Don owned Plumline, a cycling apparel company, which is why this event (and the original “Ultimate Kamikaze” have “Plumline” in the title.)

  • We also got ride beta from  Charlie Kelly, one of the founders of NORBA, who was also instrumental in the race (see Charlie’s profile in the Mountain Bike Hall of Fame).  He sent over some photos and helped us locate three magazine articles about the race (Fat Tire Flyer, Mountain Bike, and Winning Bicycle Racing Illustrated).

Original “Sierra 7500″ Course Description:

There was the full 50 mile course and a 25 mile “fun ride”.  Both began in the Millpond Recreation Area and headed out towards Tungsten City Rd for a short stint, before crossing McGee Creek and climbing sandy, rocky doubletrack (offering up hike-a-bike for some), until it reached Buttermilk Rd near the junction of Hwy 168.  It continued to climb Buttermilk Rd, contouring around Grouse Mountain and past the turnoff for Horton Creek.  It continued south/east until it merged with Hwy 168, near the junction with South Lake Rd.  At this point, the 25 mile ride descended back to the start via doubletrack, some paved riding, and eventually back down the same climb the race started on.  The “full monty” continued up a short paved climb on South Lake Rd, which brought you to Habeggers Rd- (see also The Coyote Traverse), a soft, steep 4wd route that zaps your energy as it rises to Coyote Ridge over 11,000′.  Finally, you start a glorious descent down into Coyote Flats, and eventually back into Bishop/Millpond to cap off the epic journey.
