Named by Terrain Magazine’s Readers as the Best Adventure Race in the area in 2023, the Castlewood 8-Hour Adventure Race has grown to become the third-largest adventure race in the country. And it’s all happening right here in St. Louis.

What is Adventure Racing? A multi-sport, off-road, team event with no marked course. Teams must use a map and compass to navigate their way through a series of checkpoints on mountain bikes, in canoes, and or on foot to reach the Finish line.

How long is the race? Expect to cover 5-10 miles paddling, 15-20 miles biking, and 5-10 miles on foot. Please see the Frequently Asked Questions section for more information. You can also email the Race Directors at csona@alpineshop.com or jsona@alpineshop.com or post on our Facebook Event Page.
