Race Information

The Tunnel Hill 100 features a USATF/IAAF sanctioned and certified marathon course and a great place to run a BOSTON QUALIFYING TIME or a personal best. Certification # IL18001BW. The race is presented by Durbin Race Management. You will start at the same start line in Vienna, IL as the Tunnel Hill 100/50, exactly 24 hours after the 100/50 start. You’ll encounter hundreds of runners who are finishing the final miles of their 100 mile run, and everyone will have a great opportunity to cheer each other on as you work your way over dozens of train trestles, and among gorgeous rock formations.

There will be a 6 hour limit, and the race course will close at 1pm on Sunday. LESS
