11th Waldo 100K scheduled for August 18, 2012.

2012 registration opened on March 1 and sold out 5 hours and 47 minutes.  See 2012 entrants list on UltraSignup.

2011 registration opened on March 1 and sold out on April 4.

Our Forest Service permit allows for 125 runners. We will overbook with the goal of having exactly 125 on the starting line. There will be no waiting list. The number of applications accepted is anticipated to be 155-165 depending on how fast we fill. The race reserves the right to let anyone in at any time if we deem that is in the best interest of the race.

If you sign up but must withdraw before July 1, 2012, we will refund most of your entry fee. No refunds after that date.

In the event of fire or other event beyond our control that forces us to cancel the race, we will do our best to refund your entry fee, but remember that many supplies/expenses are purchased months before the race.

Proceeds from the race go to the Willamette Pass Ski Patrol. Over $43,000 have been raised in the first ten years of the race. Thank you runners, volunteers, and sponsors.
