During the centurion I was attempting to reduce the stop time, so decided to give the Gatorade a try as it was ready and being handed out as you passed by. The ride was tough (but good) and managing effort was necessary to prevent cooking the legs. I found it interesting that the leg cramping seemed to coincide with taking in Gatorade. Was the cramp caused by intolerance to the fuel, dehydration, electrolyte depletion, or, most probably, all of the preceding.
Anyone have experience with using one water bottle with high concentration of electrolyte (HEED or other) and the other with the normal concentration. After the normal bottle is consumed then use water and alternate taking from the high concentrated bottle and the water?
This tactic may work for Centurion, there are 4 feed zones approximately equally spaced on the route, so fresh water could be taken on without stopping.
