What benifit do you think it may be to "clear" your system before a race, with the effects of a laxative wearing off about 3-4 hours before a race. I figure you would be about 3-4 lbs lighter which could make a big difference in a 5k or 10k or any race for that matter. Any medical advice?
I'd advise against it for many reasons. Also, what kind of laxative are you talking about? A simple fiber supplement? Or an actual hyperosmotic or stimulant laxative? The latter types will really only serve to dehydrate you, as they'll draw water from your system to fill your bowels in order to provide more "bulk" flow. Either way, don't use the. Especially since you can become somewhat "addicted" to or dependend upon them. They're not something to mess around with.
Just ensure that you're getting enough good fiber in your daily diet, although you want to steer clear of high fiber meals leading up to a race. It might not be a bad idea though to choose high fiber foods (Fiber One cereal is GREAT) for a few days leading up to the race, and use that as a way to "cleanse" your system. Then back off a day or two before the race and just eat normally as you would.
