Conquer four races in 24 hours! All races will be chip timed. Cumulative results from the four races are used to determine official results.  All courses are on pavement or sidewalk and are generally flat. The two-mile course does reward participants with a tough little hill near the finish. The first 5k is around Lake Hollingsworth. The one-mile race is around Lake Morton. The two-mile race is around Lake Hunter. The final 5k repeats the course around Lake Hollingsworth. Can you run the Saturday 5K faster than you did the Friday 5K?

The Aching Quad Four Race Challenge was established in 2006.
