Relay for Life, supporting the American Cancer Society

WYNNEFIELD (WPVI) -- This is just the beginning for what promises to be a long night for these students at Saint Joseph's University.

They started walking laps around Hagan Arena at 7 Friday evening, and plan to keep going until 7 Saturday morning.

It's all for a great cause, though.

This is Relay for Life, which raises money for the American Cancer Society.
