Fun courses. Affordable and straight forward pricing (no discount codes). Simple SWAG and food. No bands, gimmicks, or other fancy extras. You think those are free? Look at how much you are paying. If you 're looking for a party, try RnR. This is just good, old fashioned, trail racing fun, the way it used to be.
*Registration includes swag (tbd), awards (overall, master, and 10yr age group), food, and the chance to win raffle prizes.

Add postponement to your registration for just $4. If the weather makes the roads, trails, or racing dangerous (this takes more than just snow and cold), or if the park determines that racing on muddy trails will cause too much trail damage, the race may be postponed. This is unlikely. Purchase insurance to get a refund if you are unable to race at a later date, if the race is postponed. Tentative make-up date Nov. 12. Otherwise, no refunds.

Race number pickup on race day only.

Course: The course will go counter-clockwise on the Gold, Purple, Green, and Red loops. Click map below for larger image. Elevation profile and detailed descriptions will be updated later.
