Based in Utah, Ragnar Events, LLC is the largest overnight running relay series in the United States. Traversing inspiring and scenic destinations around the country, these events make testing your limits a team sport. In the Ragnar Relay Series (www.ragnarrelay.com), teams of 12 run a 200-mile relay over two days and one night; in Ragnar Trail Relays (www.ragnartrail.com), teams of 8 run a 120-mile trail relay over the same time span. Participants connect in memorable relationships, conquer a challenge that could not be done alone and celebrate with medals and finish line festivities. Often called a slumber party without sleep, pillows or deodorant, this unique relay turns out crazy costumes, inside jokes, close quarters and unforgettable stories.

Begun as a single relay from Logan to Park City, UT in 2004 by college roommates, Dan Hill and Tanner Bell, now over 200,000 people have run in the Ragnar Relay Series, which boasts 21 races, including Canada, and is growing every year. read more
