Our Next Race: Cruel Jewel 100 and 50

Who are these Dumasses?

We are the Dahlonega UltraMarathon Association and we like to run really far. We plan, organize, and host events for people who like to run really far too. Ultramarathon races are running races exceeding the distance of a marathon.

Ultramarathons are for experienced runners (with much running comes much responsibility), but those who take on the physical and mental challenge find a rewarding running experience unlike any other!
