Lean Horse Ultra Start

The Lean Horse Ultra is considered to be one of the best first time ultras in the country because of the great running surface, gentle elevation changes and user friendly course.


There were many changes at the Lean Horse 100 last year.  We are working hard again this year to continue to grow the Lean Horse races.  There are many new things to come this year.


For more than 10 years, Lean Horse 100 Ultra has inspired runners of all abilities and from all walks of life, from all over the country and world come to South Dakota to test themselves over the 50k, 50 mile and 100 mile distances and new in 2014 the 30K and a Five person 100 Mile Relay.
