This weekend, 400-plus handstanders will attempt a monumental feet feat: to break the world record for the largest group handstand by simultaneously turn upside down in Dolores Park on Saturday.

Team Handstand—the folks behind such zany events as the SF Hunt and the Mario Kart–inspired races at Kartwheel—was founded by four local friends (Sam Goldstein, Josh Zipin, Gil Levy, and Kyler Evitt) with a fondness for adventure and wild times.

On Saturday, July 15th, you could become part of history by joining Team Handstand at Dolores Park for an attempt to shatter the world record for the most people doing a handstand at the same time. The current world record is held by Braderie Comity of Wevelgem, a group of passionate Belgian handstanders who took the title when 399 people went head over heels all at once in September 2006.

Care to take a stand? Arrive at Dolores Park at 1pm sharp for handstand lessons, a bit of friendly competition, and the chance to win $500 in prizes. The big attempt at the world record will go down at exactly 1:33 pm, so be ready—and be ready to party afterward while the group counts all the feet in the drone footage. ("There will be hella drone footage.") The results will be announced at 3pm.

Raise your foot if you want to break the group handstand world record!
