worried about cramps
I am scheduled for a HIM in September, and have been swimming regularly since February. I have probably completed ONE swim session without cramping in my feet. I am well hydrated, have been taking calcium and magnesium religiously on a daily basis to get rid of the problem, but it persists. (i drink more than 3 liters a day on average, more if I ran longer or when it is hot.)
Cramping usually occurs after 45-55 min., mostly in my toes. I swim in pools, and the water is fairly warm. I will be using a wetsuit for HIM, but need some reassurance at this point.
In general, I have very tense muscles in my feet, have been running for more than 20 years on a daily basis. (never had a running injury.)
All advice is welcome.
I started using fins last week, doing 10 lenghts with the kickboard at the beginning of my workout. Is this useful?
