half ironman races, not in Ironman nor olympic distance races. Has
happened twice at Wildflower and to a lesser degree at Buffalo Spring
Lake, both of which have hills at the begining of the run. The cramping
has caused me to stop for stretching and massaging. Afterwards, I can run
at my desired race pace. Very discouraging because in the Wildflower cases
I have dropped out of Ironman qualifying spots because of short lived but
I have looked at the obvious problems; hydration (I try to drink about 32
ounces of sports drink per hour), electrolyte defienciency (again, I drink
a sports drink containing electrolytes), and previous muscle
fatigue/trauma (I taper well and get massage as much as I can afford).
I am beginning to believe that it has something to do with the 2.25-2.5
hours of hammering during the bike portion of a half ironman. I do not
cramp in olympic distance where the bike is shorter nor in Ironman where
the pace is slower, about 5 hours. My longest time trial training efforts
are about 60-70 minutes. I thinking that I need to increase them to about
90-120 minutes to condition my body for that long of a hard effort.
Although I do ride a great deal in flat terrian, I do ride a significant
portion in hills for specificity of training.
Any thoughts or advice would be greatly appreciated.
