The Colfax Marathon races may have been cancelled in May of 2020 but the race hosted a successful Welcome Back 5K last Saturday to a sold out field. More than 600 runners and walkers finished the 5K at Denver’s City Park. Waves kicked off at 8am, 9am, 10am and 11am with a few runners starting at a time. Results can be found at www.HalSports.net. Here are photos from the event.
