About this race
Event Overview
Join us at the historic JM Collingwood Barn, west of Pretty Prairie, Kansas in the beautiful Ninnescah River Valley! The largest barn in Kansas, built in 1913, is a hidden gem and you'll be in awe of its architectural craftsmanship!
Race Route
- Direction: The routes will head south from the barn into Kingman County this year, exploring the roller hills, bluffs, and open grasslands between Murdock and Kingman.
- Road Conditions: The roads in our area of Kansas range from fast hard pack to light sand over hard pack with some stretches of deeper sand that change in firmness with rainfall amounts.
- Challenge: We do our best to limit the amount of deep sand, but it is all part of the challenge in the Ninnescah River Valley.
