“Grit, endurance, temporary loss of sanity. You might need all of these if you want to attempt Grindstone. If you want to finish, well, just keep in mind this is, without a doubt, the hardest 100 miler east of the 100th meridian. Now that you’re hooked, Grindstone is going to be an incredible adventure for each and every entrant. From the beautiful start/finish location at Camp Shenandoah to the monster climbs and the solitude of single track ridge running, you just can’t beat Grindstone… but you can try!”

Course Description (Wikipedia)
Grindstone 100 miler is an annual 101.85 mile long ultramarathon that takes place on trails in Virginia’s Allegheny Mountains, usually the first weekend of October. The race starts at Camp Shenandoah, a local camp of the Boy Scouts of America. Beginning at Camp Shenandoah, this out-n-back course ascends and descends Little North Mountain before climbing over 2400 ft (740m) in 4 miles (6.4km) to the summit of Elliott Knob. The course then proceeds north following the ridge-line of the Great North Mountain range, crossing over to and following the Wild Oak Trail before continuing north to the summit of Reddish Knob. Runners continue north to Briery Branch Gap before retracing their steps (without summiting Elliott & Reddish) back along the course to Camp Shenandoah. Runners climb a cumulative total of 23,200 feet (7,140m) and descend a total of 23,200 feet (7,140m) on mountain trails before reaching the finish.
