Relay Racers

A bus will shuttle racers from the start to 16½ Road next to Rim Rock Drive. All racers must exchange places through a physical touch, i.e. High Five. The bus will stay at 16½ Road until all relay racers have exchanged places then return to Circle Park for the finish line activities.

Please coordinate with your relay partner on exchanging goods/clothing items at the relay exchange point. We recommend the first leg relayer have the second leg relayer take their extra layers/etc. on the bus to the exchange point. Then have the first leg relayer take the second leg relayer's extra stuff on the bus back to the finish line.
