Pre-Race Shakeout

This Sunday-morning shakeout keeps things simple and social: an easy out-and-back run of about 5K that traces a stretch of the Boston Marathon course. Joachim Cassel leads alongside local Boston community runners, making it a low-pressure way to loosen up and preview the route before race day. Doors open at 8:30 AM at The Trackhouse, with the group heading out shortly after.

Good to know:

• No bag check is available, so plan to carry what’s needed or travel light
• Arriving at doors-open helps with a smooth start and pre-run meet-up time
