Divisions Offered

The 508 has a division for every kind of ultra cyclist! We offer solo, two-person relay, and four person relay, plus an eight-person tandem relay division. There's an epic racing opportunity and spiritual odyssey to be experienced in each division!

There are two separate sub-divisions, men's and women's, sharing the same route at the same time, as well as tandem, relay, fixed gear, Classic Bike, and recumbent / HPV categories (see 2D in the Rules Section for classes of recumbents and HPVs allowed and 2E for fixed gear guidelines), along with age group designations from 10+ through 70+. Here are the current categories. If you would like to enter in a new, different category, please contact the race director in advance to discuss that possibility. (See Race Rules for additional information.)
