All entrants in timed events will be issued with a Velcro strap to secure an electronic transponder to their left ankle in. The electronic transponder is inside a blue plastic housing that is threaded onto the Velcro strap so it can slide to any position regardless of ankle size. If worn correctly, these Velcro straps CANNOT come off. All users are responsible for wearing them correctly, so please follow these instructions. Lost timing bands must be paid for.
