The Yamacraw 10K trail race follows the Blue Heron Loop Trail at the Blue Heron Mining Community in Big South Fork National River & Recreation Area. The course features gorge overlooks, river views with Class IV whitewater rapids, rock overhangs, waterfalls and sandstone bluffs. Several wooden step ladders appear throughout the course that runners will have to traverse including the a cave-like passage called “Crack-in-the-Rock”. The course might be a lot shorter than it’s sister race but it’s no slouch. The Yamacraw 10K starts with a challenging uphill climb of close to 775 feet within the first 1.5 miles offering runners of all ages and experience both a challenging and enjoyably scenic race.
