Coming off last year’s tremendous turnout, the second annual Escape the Cape triathlon will take place in Onset on Saturday, June 4 at 9:30 a.m.

Hosted by race director Max Performance, the course will feature a 1/3-mile swim, 10-mile bike, and 3.1-mile run.

The course, which boasts views of Onset Bay, Little Harbor Beach, and the East River, attracted 500 athletes last year.

While the race has already sold out, onlookers are invited to cheer on the athletes.

The triathlon will begin at Onset Pier with the swimming portion of the race, and will finish at the Band Shell after the run.

A post-race festival will include a barbecue that is free to all participants and costs a small fee for spectators.
