1) Simply sign up for an in person race or challenge, show up at race, check in and race in our 8th Annual River's Edge Endurance Challenge!
Last year we changed our 5 mile race to 5K (3.1Mile) race and it was a hit! Basically the whole race is on the River's Edge Trail system! You will love it!
Our 3-hour challenge and a 6-hour challenge remain the same, and still use a 5 mile loop. How many 5 mile loops can you do in 3 or 6 hours?
Here is a link to a map of our in person race. <-5mile.
