Yamacraw 50k

Saturday April 7th, 2018 7:30 AM

The Yamacraw 50k 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 closer to a 53K coming in close to 33.1 miles. 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 singletrack trails and scenic landmarks that include stunning rock overhangs, natural arches, and wonderful waterfalls. Runners will enjoy multiple water crossings as they run alongside the Big South Fork Cumberland River and adjoining creeks. The race ends with an iconic crossing over the river on a 100 foot high pedestrian bridge that leads runners straight to the finish. The 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. At a modest 3,809 ft feet of elevation gain, the Yamacraw 50k is challenging but still a great race for those looking to complete their first ultra or those gearing up for their new race calendar.

**There is a 11 hour cutoff time for the Yamacraw 50k

**Portions of the proceeds benefit the National Park Foundation  and National Forest Foundation.

Race Day Check-in and Shuttle

Since the 50k is a point-to-point course, runners will be shuttled from the race check-in at the Stearns Heritage Hall to the start (Lick Creek Trailhead). The shuttle will leave the Heritage Hall at at 7:10 am. Check-in will be at the Heritage Hall  from 6:00 to 7:00 am. A post race shuttle will be provided to runners from the race finish at Blue Heron to return runners to their vehicles in Stearns. All 50K participants are asked to park at the designated parking areas in Stearns adjacent to the Heritage Hall.

Runners will not be able to leave anything on the buses, but we will have a vehicle available to transport “warm-up” clothes from the start back to the Stearns Heritage Hall, if there are things you’ll want at the start, but not once the race starts.


We will have unique awards for the top male and female finishers.
All 50k finishers will receive a finishers award.
