40M Details

Distance: 38.4
Elevation Gain: 6,254 ft
Start Time: 6:30 AM EST
Cut-off: 12 hours

The Yamacraw 40M is a point-to-point trail race that begins at the Lick Creek Trail in Daniel Boone National Forest and ends at the Blue Heron Mining Community in Big South Fork National River & Recreation Area. The actual distance is approximately 38.4 miles with an elevation gain of 6,254 feet. The course traverses some of the most beautiful trails in the southeast including the Sheltowee Trace Trail, Kentucky’s longest trail. Runners will be treated to miles of magnificent single track trails and scenic landmarks that include stunning rock overhangs, natural arches, and several waterfalls including Princess Falls and Yahoo Falls, Kentucky's highest waterfall. Runners will encounter multiple water crossings throughout the course. While there are many creek crossings throughout the course, there are two major water crossings the first coming at mile 18 at Rock Creek and the second as runners enter the Blue Heron area at around mile 32. Runners will come into the finish area for the final aid station then follow the Blue Heron Loop Trail 6.6 miles until returning to the finish. The 40M course offers some challenging climbs towards the second half of the race but is fast and highly runnable which can be a challenge in itself.

The shuttles will leave the Heritage Hall around 6:00 am race morning. Check-in will be at Heritage Hall from 5:00 to 6:00 am. We will begin loading the shuttles around 5:50 AM. Finish line shuttles will be provided to get runners from the race finish at Blue Heron to return runners to their vehicles at the Heritage Hall.

Runners will not be able to leave anything on the buses, but we do allow for one drop bag which can be accessed at mile 32 and then again at the finish. Drop bags should be left at the Heritage Hall at packet pickup or race morning before getting on the shuttle bus. Drop bags will be transported to the finish by race staff.

Course Markings

The 40M will be marked with PINK & YELLOW/BLACK checkerboard flagging. Markings will be spaced maximum every .25 mile with more heavily markings at any turn or crossing trail. The race organizers will do everything they can to have the course marked well for race participants the day of the event. During the on trail sections of the course, runners must stay on the trail. No switchback cutting!

*Note, while the course will be marked, these trails will still remain open to the public. Please be courteous to all park visitors.


Due to the nature of the course being in a river gorge area and the chance for chance for flooding or high and swift water we may have no choice but to change the course in order to limit risk to runners. In the event extreme weather, flooding, or dangerous river currents on race day, the race directors reserve the right to alter the 40M course to keep runners safe.

Depending on the condition of the course, The PLAN B COURSE will mostly likely be a double loop of the first 16 miles of the course and the addition 3.5 miles back to the start. More details will be provided closer to race day should we have to go to PLAN B
