2025 Results

On behalf of the Run for the Stripes board of directors, we are thrilled to share that as a result of all of your efforts — fundraising, volunteering, and sponsoring — we raised a record-breaking $95,000 and donated it to the NET tumor program at the University of Pennsylvania Abramson Cancer Center. This brings our lifetime total to $805,000.

We had 1,043 registrants, 816 in person and 227 virtual. Participants joined from over 20 states — even from a cruise ship. Mark November 7, 2026 on your calendar to be with us at the Zoo again next year!

Warm Regards — Jim Eisner, Lori Canzanese, Andy Steinfeld, Jean Binkovitz

What is a NET?

Neuroendocrine tumors are rare cancers that form from hormone-releasing cells. Often called the “zebra” diagnosis — that’s why we run for the stripes.
