Im not a runner/cyclist or anything like that (FAR FROM IT! lol). But with all the doping scandals surrounding Lance Armstrong and that other dude who just got popped... It got me curious.
What type(s) of gear do these people run, in order to excel in these high endurance sports? I would guess they need something which would delay oxygen deficiency somehow, without adding the unnecessary bulk and heavy (unnecessary) muscle mass.
Is there a thread on this subject that someone can point me to?? I couldn't find one in the search/ Nothing specific anyway.
