REGISTRATION FEE: The price is $75 non refundable and the service fee is $5.00, so the total will be $80.00. For ten-timers, previous overall winners, and water haulers, please choose the appropriate category so you are not charged. Non appropriate folks entering the Previous Overall Winner / 10+ repeat finisher category will not be officially registered.

ESTIMATED TIME: For estimated time, you need to put a decimal number, i.e. 4, or 5.5, or 6.25, which refers to hours. If you have never done it before, but have done a marathon, add about 1/3 to your marathon time, i.e. you run a 4 hour marathon, you'll do around a 5.3 hour Ridge Run. Doubling your round trip M-to-Baldy-to-M time is also a good estimate.

WAVE STARTS:  To prevent congestion at the start, we have 5 waves starting every 5 minutes at 7:00. Wave time is deducted from finish time. Wave 1 is for highly trained athletes. Wave 2 is for those who expect to finish in 4 1/2 to 5 hours. Wave 3 is for 5+ to 6 hour finishers. Wave 4 is for approximately 6+ to 7 hours. Wave 5 is for 7+ hour finishers. We will use your guesstimate and other factors in determining waves. If you want to be with someone, plan ahead and please submit the same estimated finish time and wave. We cannot guarantee buddies. We'll tell you your wave a week before the race.

SAFETY & ORIENTATION:  Runners, especially first timers, NEED to attend the pre-race meeting at 3:00, 4:00 or 5:00 PM Friday night at the M Trailhead to receive updated information and review maps.

Please, NO DOGS, bring water, wear layers and a hat. If you must drop out of the race, PLEASE let someone know of your decision and location so we don't spend hours trying to rescue you. Show your bib number at each checkpoint.

REFUNDS & CANCELLATION:  There are NO refunds for any reason. Funds are donated to good local trail causes. Please let us know if you need to cancel. We must keep track of each runner on the mountain, so it's very important to know who is out there. To cancel, email mail to:
