In 2012, five individuals and two relay teams inspired by the 110% Play Harder Challenge ran 110 miles and raised more than $115K. In 2023, the Challenge continues!  Athletes will cover 110 miles to finish breast cancer. Race the traditional Ultra Marathon in-person, or take on the miles as a virtual challenge over time with our DONNA 110 Mile-A-Day Challenge.

February 4 – 5, 2023
