bad day of training....

well I was having a good swim today. I was 22 minutes into the swim when I got maybe the biggest cramp I have ever had in my left calf. Hurt so bad I was yelling under water. I finally got it stretched out and tried to continue but it was to late for me. The cramp would return if I tried anymore. I hope that things like this are not normal. :(
