Blood Rock 100

Embark on an unforgettable trail running adventure at the Blood Rock 100, held on December 5, 2026, in the rugged beauty of Oak Mountain State Park in Pelham, Alabama. Known as Alabama's premier mountain trail adventure, this race offers a true test of grit and spirit across 50M, 55K, and 25K distances. Runners consistently describe the course as extremely technical, very steep, and demanding, with the 100-mile race featuring an impressive 17,196 to over 20,000 feet of elevation gain across its two loops. Expect to navigate approximately 90% single track trails, winding through remote backcountry sections, past stunning mountain lakes like Summit, Demopolis, and Belcher, and tackling legendary climbs such as the "Crack-in-the-Wall."

The Blood Rock experience, starting and finishing at the scenic Cabins on Tranquility Lake, is renowned for its challenging terrain. Runners should be prepared for rocky paths and roots often hidden beneath a blanket of fallen leaves, especially during the long December nights. Despite its "Brutal" reputation, the course is also described as tough but fair, with a well-marked route thanks to flags and reflective markers. Aid stations, strategically placed every 5 to 8 miles, provide exceptional support with hot food available day and night, cold drinks (runners should bring their own cups), and even a full breakfast for 100-mile finishers. Crew access is excellent at most aid stations, with provisions for overnight park entry.

Typical race day conditions in early December offer highs around 61°F and lows around 39°F, with a modest 14% chance of precipitation, creating ideal cool weather for tackling the arduous climbs and technical descents. Whether you're aiming for your first ultra or a seasoned veteran seeking a profound challenge, the Blood Rock 100 promises an immersive journey through Alabama's finest trails.
