Hanging up your long-distance shoes?
We know that not all of our participants will want to go the distance year after year. Even if you're not running a marathon this year, there are still opportunities to get involved in other American Cancer Society events such as Relay For Life®, Making Strides Against Breast Cancer®, and many other exciting opportunities.
