Ready to hula? With the goal of surpassing the current world record of 2,450 simultaneous hula hoopers, attendees are invited to spin in unison at Discovery Green. Participants are required to raise or donate $100 to take part in the Guinness World Record attempt, with all proceeds going to more than 5,500 families with special needs served by Easter Seals Great Houston.

The Care2Spin Hula Hoop Challenge is a preview to the Sept. 17 Care2Spin bike spinning marathon, where individuals can engage in any activity that spins to raise money for Easter Seals Greater Houston and their partners.
