"We basically have two races going on at the same time," Seiler said, "the running race and the walking event. Some walkers are serious, but a lot of them just want to enjoy the scenery."

High school cross-country teams are encouraged to compete.

Rim Run registration is $20 if postmarked by Aug. 18, and $25 afterward. Participants may register at Ruby's Inn the evening before the race from 6 to 8 p.m., or from 7 to 8:30 a.m. on race day.

The entry fee includes a Rim Run T-shirt, post-race lunch, entertainment, awards, random prizes and a ticket for free admission to the Bryce Canyon Country Rodeo.
