In 2012, five individuals and two relay teams inspired by the 110% Play Harder Challenge ran 110 miles and raised more than $115K. In 2021, 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.

DONNA 110 Race Instructions

Responsibilities and Timing

Individual participants will be manually timed by a course marshal for “Day 1” from the start of the race through the completion of the first 83.5 miles.

Runners will then run the DONNA 26.2 Marathon event and will be chip timed.  The official marathon time will be added to the stage 1 time to calculate final standings.

For questions about this event, please contact us.

Qualification Criteria

DONNA requires all athletes participating in the DONNA 110 to have previous ultra race experience of at least 50 miles within the race’s cutoff time.  Proof of experience will be requested upon registration.
