Today is Global Running Day, the day when any real runner comes down with a terrible viral illness that forces them out of their cubicle, and into the sunlight for a midday 5-mile run. I mean, if it’s training, it still counts at work. Whatever race you’re training for, we gathered up some discount codes from some of our favorites. (P.S. a lot of these races will have a summer price increase, so you’ll never snag them this cheap again).
