Okay, so this is a little outside of NorCal, but Nevada doesn't get much MTB love . . . As part of the made-for-TV Nevada Passage "adventure series", Nevada Commission on Tourism will be hosting a NORBA sanctioned Bloody Shins Trail MTB race on May 6th, 2006. The race will be held outside of Winnemucca, NV and consist of multiple laps (depending on category) of a 14 mile XC course. The MTB race is part of a larger race series which also includes trail running, kayaking and an ATV jamboree (?).
Event: Bloody Shins Trtail MTB RaceUPDATE (04/20/06): A thread over at MTBR has some more details. Looks like 1300 ft of climbing per lap.
