New this year, all participants who finish the 5 mile or 1 mile run will receive a medal. To receive Radnor Run event t-shirt, you must raise $100 or more.

TEAMS: At least three people are needed to form a team in the 5-mile race. However, teams may have more than 3 people. Using the cross-country method to calculate team time, the times of the top 3 runners on your team will be calculated to get your team time. Awards will be presented to the Fastest three teams. Awards will also be presented to Top Friends & Family Fundraising Team and Top Corporate Fundraising Team.

SCHOOL TEAMS: Organize your school to participate. All registered participants will be counted- including 5-Mile, 1-Mile and volunteers - for eligibility for Top School Trophy. This is a traveling trophy which the winning team will house at their school for the year.

th Annual Radnor Run will fund lung disease education, advocacy and research in Greater Philadelphia. These efforts will include research through the Airways Clinical Research Center at Temple Lung Center, Johnathan Whetstine, M.D. and Alfonso Bellacosa, M.D., M.H.S. at Fox Chase Cancer Center and Megumi Shigematsu, PhD at Thomas Jefferson University. Funds raised also supports the Lung Association’s efforts to end lung cancer, and those affected by lung disease, including COVID-19. In 2020 the Lung Association launched a $25 million COVID-19 Action Initiative to end COVID-19 and defend against future respiratory virus pandemics. 89 cents of every dollar raised by our organization goes directly to education, research and advocacy.

Many employers will match donations made by members of their staff. Please check with your Human Resources and/or Finance department to see if they have a matching gift program. Matching gifts can be submitted via email to your event manager Larissa Fallon (Larissa.Fallon@lung.org).
