COURSE CUTOFF TIMES
All Marathon & 50K participants will start at 7:30 AM. Participants may choose at the decision point (~27.7 miles) to opt for the marathon or run a loop around Clopper Lake to complete the 50K. After 3:25 PM, the 50K option is no longer available at the decision point and all remaining participants are diverted to the Marathon finish. Cutoff times will be strictly enforced due to our permits.
When attempting to pass another participant or trail user, you should offer a polite warning such as "on your left" prior to carefully passing. Please ALWAYS pass on the left. On the other hand, if another participant is looking to pass you, kindly move to the right and let them by.
Please do not, under any circumstances, throw trash on the trail or anywhere other than a proper receptacle. You may carry your trash with you or leave it at one of the aid stations. Litter left on the trails or in the parks will jeopardize our acquisition of future permits and if seen, will result in disqualification from the race.
Finally, please thank the volunteers. Without them, we wouldn't be able to offer this event. Their hard work and dedication (especially in adverse weather) is greatly appreciated.
All participants MUST stop at road crossings. Cars do still have the right of way during this event. Course marshals will be present, but their job is not to stop traffic.
Please carry a cell phone. The race is on single-track, dirt trails that may be icy, snowy, or muddy with rocks, roots, and slick wooden bridges. Please pay attention and use caution at all times. With that, please do stay on the designated trails. They were constructed to eliminate erosion, protect vegetation and keep soil on the trails.
If you find yourself injured, please inform another participant and ask that they notify race officials at the next aid station or checkpoint.
Headphones are discouraged during this event. Their use makes it difficult to hear people or animals coming up behind or beside you.
If for any reason you find yourself unable to finish the race, please make your way to the nearest aid station and let the volunteers know. If you don't have a phone, they can assist you in calling a friend or a lift service to transport you back to your car.
