The steep and rough Repack Fire Road in Fairfax, Marin County,
California is where mountain biking started. It got its name
from the smoke that billowed from burning grease and the subsequent
need to repack the hubs of early coaster-brake bikes cruising
this classic downhill.
The first formal race down Repack was held in 1976. For the
handwritten results of those early races, see Charlie Kelly's
records. These are the earliest documents in the sport
of mountain biking.
Thanks to Rob Nilsen for sending three of the photos.
