The Wanderlust Festival returns to Brooklyn for its second year. This “mindful triathlon” brings three events together at the Prospect Park Bandshell: a 5k run, an outdoor yoga experience, and a guided meditation -- but with a twist. Unlike most triathlons, Wanderlust places community above competition, inner peace above power, and self-awareness above strength. At this triathlon, it’s about slow food to fast run times.  Winning is measured in laughs shared and new friends made.

And unlike many events offering yoga and meditation, Wanderlust 108 combines your practice with a whole lot of fun. From live bands and DJs on the main stage, to lawn activities like hooping, slacklining and acroyoga, to our local food and craft vendors, there’s a lot to do when you’re not on your mat.

Find out more information and register on the Wanderlust website.
