This is STL’s Original 100-mile trail ultra!! The Shippey will rotate directions each year going CW odd years & CCW even years. You be the judge which way is easier by running both ways!

The course is set up as 20mi loop(run 1x for 20mi, 3x for 100k and 5x 100mi), the full 20mi loop is done in 5 legs ranging from 3.2-5.8 miles. There is approx. 1 mile of pavement over course of 100mi. There will be 2 aid stations setup on the course which you will venture too multiple times. Each leg varies from the others offering steep climbs, ridgeline running, long and short steep descents as well as creek bottoms, pine floor, and jeep roads with approx. 75% single/double track, 25% jeep roads.

Every 20mi loop is approx. 2,900′ ascent,40mi approx. 5,800′, 100k approx. 8,700′ & 100mi approx. 14,500’

100m/100k/20mi Relays:

The most affordable relay event around with the best swag and awards. Shoot…we even let you eat from our aid stations. You seriously will not find a more accommodating or fun trail relay! Think Ragnar style at a 1/3rd of the cost with less restrictions and more fun!! 100 mile/100k/20 mile options with all using teams of 5. The 20 mile loop consists of 5 different legs to complete. Every runner must run AT LEAST 1 leg depending on the teams distance. Example, the 20 mile teams will all run 1 leg to complete the 20 mile relay race. But for the 100 mile or the 100k, the teams can choose how to tackle all of the legs that make up their full distance in any order they would like so long as every runner AT LEAST runs 1 of the legs.Relay races will be chip timed via an ankle bracelet which must be worn outside of clothing and exchanged at each trade off of runners. Each Team is responsible for the timing chip and is required for accurate timing
