Hamstring Cramp

evo3ben

While racing at Oktoberfest i got cramp in my left leg hamstring which put me on my back at the side of the track in agony. Nearly ended my race.
Problem now is that it still hurts a month later. I train on average 9hrs a week but no problems during training. Its off the bike it hurts at times and has nearly cramped up a couple of times, once when getting up out of a chair and other was when walking in a shop :?
Not sure whats going on and ideally dont want to stop training, any advise would be much appreciated!

Just to add, i drink enough water, eat 2 bananas a day and take electrolyte (Elete) tablets.

do you do any hamstring specific work off the bike ?

if not, then start doing some. Presumably you are stretching the area as well ? if not, then start doing that as well
