There are two types of Ragnar races. One is a through road relay race, where you get a team and some vans to follow and you relay race from one place to another. For example, there’s one that goes from Long Beach to San Diego. You’ll see these painted white vans chasing after people in costume as they run along.
The other type of Ragnar is like the one I just did in Snowmass. Instead of going from one place to the next, you camp out and do trail loops that all start and end at the same relay station.
