Subject: Lower back cramping I'm a big competitor at 205 and just completed my first Tri on Saturday (.6, 28, 6.55 ). I experienced lower back cramping and spasming during the first 1/2 mile of the run and couldn't shake it. Caused me to have a survival run and an average mile around 9.5 min/mile (I'm usually around 8-8.5 on long runs of 4+ miles ). This suprised me b/c I felt great on the bike and swim. I did not experience fatigue or cramping in other muscle groups. I was well hydrated and consumed Gatorade and Gels before and throughout the event. I've done "mini" tri's during training to get used to the transition from event to event with no concerns. I'd appreciate any thoughts.
