Check out the "mindful triathlon" in Brooklyn this weekend (with free meditation and yoga!)

Feeling a bit stressed? School is back in session, the vacationing masses and cramming back into the city (and the subway) and summer is making its retreat, so we don't blame you for being a little on edge. Luckily, the folks at Wanderlust are heading to Prospect Park this Sat 13 to present Wanderlust 108, the world's first "mindful triathlon." Slightly more relaxed than the usual exhausting swimming-biking-running affair—we're getting tired just thinking about it—the event consists of a 5k run, a guided meditation session and a 90-minute yoga class. The day will also feature uplifting talks from retired NFL player Keith Mitchell and beloved yoga guru Elena Brower (have a look at Brower's thoughtful contribution to Time Out's #SaveNYC), musical selections from chilled-out groove king DJ Drez and a live performance from the High and Mighty Brass Band.

If you're the sort that enjoys a jog in the park, pick up a premium ticket for $78, which gets you into the 5k run (plus other fun stuff, like priority yoga mat placement and a gift bag), but if you're just looking to show up for the meditation, yoga and tunes, you can register for free online. Visit the Wanderlust 108 site for more details and the full schedule.

But why stop there? Check out these three additional mindfulness activities (plus even more in our guide to spiritual events in NYC) and grab a little serenity this weekend.

Maha Rose Fall Open House
Holistic healing center Maha Rose opens up its Greenpoint HQ on Sat 13 for a day of discounted treatments—including acupuncture and Reiki—a free laughter-yoga class and a concert by singer-songwriter Sonya Kitchell.

The Tipi Project
If you haven't yet gone, head to Havemeyer Park, where the Tipi Project has been hosting craft workshops and yoga classes in a Sioux-style tipi. (The full schedule is listed on tipiproject.com)

Marble Collegiate Church
If a 5k run sounds like a little much, maybe walking is more your speed. Visit one of the only permanent indoor labyrinths in the city for a little self-reflection and meditation.
