Registration remains open for the second annual Rio 24 Hours of Steamboat mountain-bike race.
Katie Lindquist, one of the race's directors, said organizers are accepting registrations through Friday night at the event packet pick-up.
Riders have not been allowed on the course until it officially opens with tonight's Town Challenge Thunderhead Hill Climb.
The 24 Hours of Steamboat packet pick-up is from 3 to 8 p.m. Friday at Ski Haus, at U.S. Highway 40 and Pine Grove Road. Friday is the only day for packet pick-up.
The late registration fee is $175 per person for all divisions.
A Colorado Search and Rescue card is required to race in Saturday and Sunday's event. Routt County Search and Rescue will be on hand at the registration table to sell cards for $5.
The 24 Hours of Steamboat is a nonstop mountain bike race from noon Saturday to noon Sunday at Steamboat Ski Area.
Men and women can compete solo or with teammates. A 12-hour division also is offered. The individual or team with the most laps completed is the winner. Solo riders will compete for cash prizes. Other divisions will compete for awards.
The race divisions offered this year are: men's and women's solo pro/am, duo class, four-person pro/am (two males, two females), four-person open (male, female, co-ed and tandem) and five-person open (at least one female).
Junior classes also are allowed, though no junior younger than 18 can compete in the solo or duo 24-hour division. Juniors may race in the duo 12-hour division with an adult as their partner. Twelve is the minimum age to compete in any division of the race.
A prerace meeting is at 10 a.m. Saturday near Gondola Square. Everyone is welcome to attend, but the team captain or co-captains are required to attend. The rules are posted at www.rockypeakproductions.com.
Volunteers are needed to help with the event, Lindquist said. She promised fun for those who come out to help.
"One thing that is unique about this race is we have a lot of prizes," she said. "Everyone is fair game, including the volunteers. They must be present at the post-race party. We have bikes, Camelbaks, clothing. You don't have to win to get a great prize."
People interested in volunteering need to e-mail the day they want to help, the time, the number of shifts, contact information and T-shirt size. Those living in town can sign-up at Orange Peel Bike Shop and Ski Haus. Anyone can sign up by e-mailing firstname.lastname@example.org or by calling 879-0480.
