Prizes Awarded! NEW!
Medals will be awarded for 34 categories, including 16 age groups for men and women, fastest overall man and woman, oldest and youngest riders, Tandem and Unicycle. We are currently working with sponsors to provide prizes for these categories as well.

Prizes fueled by Hammer Nutrition: 1st, 2nd, and 3rd place categories in 16 age categories.
Special prizes for fastest man and woman wearing full Hammer Nutrition kit!

Exciting New Venue!
We are planning a BIG venue with vendors, beer, wine and food at Oak Hill Park. Turnaround time at the top will be quicker, so that riders can enjoy the party! If you are a competitive rider, or just a weekender who wants to challenge yourself, this is the ride for you!!
