A Workout for St. Jude is a fundraising event hosted by health and fitness clubs nationwide, which collect pledges and donations via special workout sessions or classes. Some acquire pledges based on pounds lifted, bike miles ridden, minutes walked and other exercises. Proceeds benefit St. Jude's Children's Research Hospital and its ongoing fight against childhood diseases. The local incarnation takes place at City Gym; interested participants should call 727-898-3302 and speak with Tera Guzman. Wed., April 30, 33 Sixth St. S., St. Petersburg, stjude.org.
