AUBURN, Ala. (AP) — Heisman Trophy winner Bo Jackson is leading his third annual charity bicycle ride. The "Bo Bikes Bama" event is being held Saturday with Auburn as the starting point. That's where the Alabama native played football and baseball for the Tigers before going on to the NFL and major league baseball. Riders pay to participate and can choose either a 22-mile or 62-mile ride. Both routes go through the Auburn University campus. Celebrity riders including former pro baseball player Ken Griffey Jr., Olympic skier Picabo Street and the NFL's Donald Driver are set to participate. The ride raises money for the Governor's Emergency Relief Fund, which was established after the deadly tornado outbreak of 2011. Promoters say the rides have raised more than $700,000 for storm relief in the state.
