The John Hancock Sports and Fitness Expo opened its doors today, allowing runners and members of the public alike to check out the latest in sports nutrition, apparel, and technology, while celebrating the beginning of Patriots’ Day weekend. This year, as always, Hynes Convention Center is chock full of vendors showing off wares—and offering plenty of free samples.

We checked out day one to give you a taste. Like what you see? The event will be going strong until 7 p.m. tonight, and again from 10 a.m. to 6 p.m. tomorrow and Sunday.

Here are scenes from the Boston Marathon Expo 2016:

Try out a new kind of elliptical from Gym Source. The trainer emulates a runner's movement and arc to provide a cross training workout with less impact.

Try out the NormaTec Pulse Recovery System to get your legs ready to run, or spectate, on Monday. The system helps improve blood circulation in your muscles, and feels like a massage.
