Pasted from an e-mail from a friend of mine.<br><br><i>I took the advice from an article in Runners World called "The Trots"……<br><br>
Calcium is the great acid neutralizer, and my problem comes at about the 25-30 km mark when a significant amount of lactic acid has been dumped into the gut (since this is the body's fastest way of getting rid of it). I have been taking 500 mg pills of calcium/magnesium 2x per day for the last 3 weeks, because apparently the body needs magnesium to absorb calcium. I am upping my intake to 500 mg 4x per day this week. When I did my 33.7 km run I did not experience any cramping, when normally I would have been doubled over by that point.<br><br>
I am also trying to reduce bread (I can't eliminate it) but I haven't been very disciplined….</i>
