The 5K Run for the Future to Benefit the ROI is an annual event that takes place on the Monday morning of the ASTRO (American Society for Radiation Oncology) convention. The race generally attracts physicians and other vendors who are attending the convention, and is not open to the public. Runners are all adults. The 5K is hosted by Radiation Business Solutions (RBS). RBS incurs all costs for the race so that all proceeds (sponsorships and registrations) benefit the ROI.
