Each team will get a wrist sweatband to pass at the handoff spots, but only the person running leg 6 will need to wear the timing chip.

Each runner must run at least one complete leg, and hand-offs can only occur in the designated spots.  Teams with 3, 4 or 5 runners can divy up the legs in any order among their runners.
