Rock Hill Run & Ramble

The R4 is one of the largest footraces in the Hudson Valley, and has raised over $1,000,000 to date. The R4 benefits the Leukemia & Lymphoma Society and the Trevor Loughlin Foundation. The R4 is held in memory of Walter A. Rhulen, a dedicated runner and local humanitarian. The event benefits the Leukemia & Lymphoma Society, the Trevor Loughlin Foundation, and other local charities and beneficiaries. We hope you can join us! Run, ramble, sponsor, register to become a bone marrow donor, visit the health fair, buy raffles, eat great food, and listen to live music.
