The Giving Back Throwdown (GBT) is a monthly workout and fun competition for the CrossFit boxes in the Lake Travis area. Each month, one facility will host a team competition. The hosting box picks a local charity to "give back" to. Team entry fees are then given to that charity.
The winning box has the the rights to the GBT Trophy until the next month.
It is a great way to have fun and meet new people for a good cause.
