Distance running is so dependent on having adequate iron and hemoglobin levels, among other things. The catch 22 is that running actually places a drain on the body that can lower these levels. Anyone who foregoes eating meat is not providing the body with the building blocks it needs. For a runner, this deficiency is exaggerated to an even greater extent. A runner who eats a vegan diet probably won't be doing it very long much like a car without fuel won't make it too far down the road. I have never been vegan but at times when I merely have had lower meat intake I could feel a difference. If you ask your body to train hard you need to support it with adequate nutrition.
This is absolute rubbish. There is no scientific evidence that meat is needed as optimal nutrition part.
I am vegan myself and have no problems with hgb/hct levels. I'm not elite, just around 16:30 5k/ 34:50 10k (started running in late 20s) but I know an 1:07 half guy that is vegan for several years and have PRed when switched from meat eater.
