Registration
Registration is now closed. Registration for 2012 will open on or about August 1,2012.
The entry fee is $35.00 most of which will go to the state and county park service and to stock the aid stations,rent port-o-pots,etc. This is a low key event. Your $35 provides plenty of well stocked aid stations but there are no T-shirts,belt buckles,medals,etc.
Refunds and Bib Exchanges: It’s just not practical to process refunds or bib exchanges. If you decide to withdraw from the race please email Doug and your $35.00 entry fee will be donated to the State and County parks instead of buying more stuff for the aid stations.
Pacers: Sorry,no pacers. Our permits with the various park services have a strict limit on the number of runners so we can’t allow pacers.
