Lace up your running (or walking!) shoes for the ROI 5k, powered by Varian, a Siemens Healthineers company! This year, ROI 5k participants will join us for a sunrise, group run along the DC monuments (perfect Instagram picture!) or complete their 5k at their convenience using any of the scenic routes we've uploaded (see POSTS for route suggestions). Visit the ROI Pod near the ASTRO Resource Center to pick-up your official event water bottle and stickers. All funds raised will benefit the Radiation Oncology Institute (ROI) – the ASTRO Foundation.
