Marathon Sports’ weekly group run gets a marathon-week twist with an exclusive test run of the LightSpray Cloudmonster 3 Hyper, finishing at the On LightSpray™ Tour Boston for an up-close look at the LightSpray™ robot and early access to shop the latest On gear. The vibe is open and social—all paces are welcome—and the finish includes post-run bites and mocktails. Marathon Sports handles gear transport from the Cambridge start to the finish so runners can go distraction-free.
