Blood Rock 100

The Blood Rock 100 is a trail running event held in Oak Mountain State Park, located in Pelham, Alabama. The race course utilizes the diverse landscape of Alabama’s largest state park, featuring ridge-top views, valley floors, and backcountry sections. Participants traverse a variety of terrains, including single-track trails, gravel roads closed to vehicle traffic, and a small portion of paved roads.

The event offers several distance options to accommodate different endurance goals:

  • 100 Mile: A 101.79-mile course consisting of two full laps with 17,196 feet of elevation gain.
  • 50 Mile: A 51.19-mile course consisting of one full lap with 8,659 feet of elevation gain.
  • 50K: A 31.18-mile course with 5,345 feet of elevation gain.
  • 25K: A 16.62-mile course with 2,885 feet of elevation gain.

The courses include notable geographic features such as the Belcher Tract, where runners pass several mountain waters including Summit Lake, Demopolis Lake, and Belcher Lake. The routes also feature the Crack-in-the-Wall climb and views of waterfalls and secluded pools.

Support is provided through aid stations positioned every 5 to 7 miles. These stations offer water, hot soup, and hot food throughout the night, with breakfast served in the early morning hours. This is a cupless event, so participants are required to bring their own drinking containers. All races start and finish at the Meeting Center located at the Cabins on Tranquility Lake.
