Competed in an Oly on the weekend and 1km into the run both thigh muscles just above the knee lock up and begin bulging. Had to pull to the side and streeeeeeeeeeetch for 30 secs before continuing. It took about 2 km to run it out but got twinges for the rest of the run. As a consequence my run time blew out by 4 mins. This seems to be happening on a regular basis. The day before the race I consumed 4litres of water and sports drink. Before the race start I had 2 litres of sports drink a gel and 4 salt tablets. I had a gel at the start of the bike and one at the end of the bike and another 4 salt tablets before the run. Drank liquids all the way on the run. What am I doing wrong????????????? :-O
I'm no pro but that seems like a lot of salt. Doesn't too much salt defeat the all that hydration. I seem to remember something about the kidneys and salt from high school biology. Do you take that many salt tablets for your regular work outs. Also, when I had a problem with cramps I read that it is important to maintain the ratio of sodium to potassium so if those salt tablets were sodium that might create a problem too. Good luck. That sounds pretty horrible.
You may be going the other way with too much salt. Gels and sports drinks are designed to replace loss - the salt tabs seem like overkill. I would also be suspicious that not enough bricks in training, not stretching before coming off the bike and pushing big gears particularly in the latter half of the ride are all sure fire winners for cramps going onto the run. Everytime I get off my bike in training I jog until the dead legs go - now it is so quick I only have to go about 50 metres. I always spin for about the last km coming into transition and stand on my pedals and stretch my calves and thighs (thrust your hips forward while standing on the pedals - takes a bit of balance so be careful the first time). Stay away from the salt tabs and keep hydrated with sports drinks and practice race effort in training - you may also be getting a bit slack in training and then going hammer and tongs in racing so you haven't really trained for that degree of effort at all!! Good luck with it - it will get better!! Dx
