A challenging course with several water crossings, approximately 12,000 feet of elevation gain, and tricky footing with lots of leaves covering the trail.

Need to Know

Numerous creek crossings. You should stay dry after Berryman Aid Station. Pack extra socks in your drop bags. Night will be cold. Have plenty of warm clothes. Please carry proper clothing with you and have additional clothing in drop bags. Don't be caught unprepared for inclement weather! Sunrise on November 4, 2017 is about 7:30 am; sunset on November 4, 2017 is about 6:00 pm. Flashlights are essential during the nighttime. They will also be necessary at the start of the race for the first hour or more.


The race is mostly on singletrack trail with several water crossings and approximately 12,000 feet of elevation gain. The trail surface varies from smooth dirt trail to moderately technical trail with lots of leaves covering the trail.

Missouri weather in November can be unpredictable. The average high temperature for November is 56 degrees and the average low is 30 degrees, but wide variances can occur (average temperatures for November 4 are highs of 62 degrees and lows of 33 degrees.) It is entirely possible to have rain, hail, sleet, snow, or ice this time of year. Be prepared for cold and possibly wet weather.

Race results will be posted as soon as possible after the race on the race website. Please be patient to see the results posted on the website as it may be a few days before we are able to verify and post the final results.

Flora & Fauna

There are lots of oak trees. Be prepared for lots of leaves down on the trail.
