ACS continues to expand its DetermiNation® Endurance Series in 2020

​Participants take on the world through newly added World Marathon Challenge

We are expanding the opportunity for people to fundraise for ACS through healthy and active lifestyle activities by adding additional events to our DetermiNation Endurance Series, including the KBC Dublin Marathon, climbing Mt. Kilimanjaro, and a trek along the El Camino de Santiago, Spain.

"Building on the success and momentum of the DetermiNation program, this coming year we will offer even more events in an ever-changing field of peer-to-peer fundraising," said Paul Purdy, strategic director, Endurance Events. "The myriad of events in our portfolio provide participants the ability to accomplish an active lifestyle goal while supporting ACS."

In 2020, two athletes and ACS supporters will participate in the World Marathon Challenge, which kicks off on February 6 in Novo, Antarctica. The World Marathon Challenge consists of 7 marathons on all 7 continents in 7 days. Only 139 people have completed the challenge since the event's inception in 2015. DetermiNation participants include Brian Cronin from Brooklyn, NY, and Keri Mandell from Princeton, NJ, pictured in the smaller photo. Both athletes have committed to an individual fundraising goal of $150,000 to support the ACS mission.

  • Brian Cronin: As an ACS DetermiNation ambassador, Brian has been running with ACS since 2012. Cancer has affected his life in many ways. In 2011, he lost his mom to ovarian cancer, and shortly after cancer took his Aunt. "This is an opportunity for me to push the limits physically and mentally, and gives me the chance to raise funds for ACS."
  • Keri Mandell: Ten years ago, doctors found cancer cells on her cervix and she had it removed, but she found out that she could no longer have kids. Keri decided to focus on what her body can do, rather then what it couldn't. She found the love and joy in running and this challenge is perfect for her. "Cancer has affected so many people that I know and love, and that has inspired me to join this ACS event. Taking part in this gives me the chance to make a difference and honor those touched by cancer."

Anyone interested in joining these athletes as they embark on 183.4 miles can participate virtually by pledging to run 1, 3, 5, 10, 26.2 or more from February 6-12, and fundraise alongside them in the spirit of  #ACSrunstheWorld.

Funds raised help ACS fund and conduct breakthrough research, and give cancer patients and their families the resources they need, like free rides to chemo, free places to stay near hospitals, and a live 24/7 helpline for answers and support.

The DetermiNation fundraising platform includes more than 90 events raising over $12 million annually. It consists of events that are owned and operated by ACS and select partnerships with third-party events such as the Bank of America Chicago Marathon, TCS New York City Marathon, runDisney series, BMW Berlin Marathon, Napa to Sonoma Wine Country Half Marathon, and many others. The portfolio offers endurance events in running, cycling, hiking, indoor-cycling, yoga, tennis, climbing, obstacle course racing, adventure trek, rappelling, and swimming.
