For one weekend every September, thousands of people break out their inner athletes to raise funds to improve the lives of peole living with cancer. 100% of funds raised by Dempsey Challenge participants goes towards providing services AT NO COST to cancer patients and their families.


The Dempsey Challenge presented by Amgen Oncology is a fundraising experience to benefit the Dempsey Center located in Lewiston and South Portland, Maine. It’s two days of outdoor fun, celebration and camaraderie. It’s a welcoming year-round community dedicated to making life better for anyone managing the impact of cancer. 


About The Dempsey Challenge
  • The Dempsey Challenge is a run/walk/cycle event and is the premier fundraiser of the Dempsey Center, which was founded by actor Patrick Dempsey with the intention of giving back to the community where he grew up, and where his mother first received cancer treatment in 1997.
  • The event takes place in Lewiston, Maine every fall.
  • The next Dempsey Challenge is September 26 + 27, 2020.
  • This will be the 12th consecutive Dempsey Challenge.
  • Together, Challenge participants have raised more than $13 million to improve the lives of people dealing with cancer.
  • Generous corporate sponsors cover the cost of the event, so every dollar raised by participants goes directly to the Dempsey Center.
