Once you have registered, please have your designated volunteer fill out the form on the volunteer page so that we have all their information and can contact them with specifics about their volunteer spot. There is a spot on the form for volunteers to pick their own time frame. Thank you!

Crew & Personal Aid: Runners may have crew support every lap. There is an area directly adjacent to the course with space for tents or canopies for personal aid stations.
Parking: Enough parking directly adjacent to the course with easy access from the course to your car any time.
Park Entry Fee: The park entry fee for one car is included in your race entry fee. Any other family members or spectators in additional cars will need to pay the State Park fee of $5.

There will be one transition area for the relay. All exchanges will need to be made in this transition area. Any exchanges not made in the transition area will result in a DNF for the team/
Warming Tent: There will be a warming/sleeping tent set up next to the Aid Station. Feel free to bring a cot, sleeping bag and blankets as you feel is needed. You may set up your own aid station in here if so desired.
For those running at night make sure to bring extra clothes, it can get pretty cold and windy so extra layers may be needed. Also don't forget to bring extra batteries for your headlamp. Even though we are inside a state park there isn't any lighting on the backside of the course so you will need to use your headlamp.


The nice thing about a timed event is that there are no DNFs (unless you sign up for 100 miles and don't complete 100 miles)
Overall winners (top 3) for each race will receive prizes.
One of the things that makes this race special is that runners will receive a special post-race award, which will be personalized and made available after the race. Anyone running 100 miles or more has the choice between a buckle OR an apparel item (to be decided at the time of registration; default is a buckle).

Local time: 12:21 AM
