2011 - no race held

2011 was to be the 50th running of the race, but dry conditions on Mt. Tam and thunderstorms in the East Bay the night before led Marin County Fire to close all of Mt. Tam above Pantoll, the night before race day. The fire service lifted the closure by late morning but it was too late to hold the race. It was the first year the race was canceled for fire risk, and coincidentally, the first year we didn't put a note about the risk of fire closure on the race website. Coincidence? Who knows, but it's going there every year from now on.
