Also another reason why I stopped running with groups, other that the fact that I don't train on roads anymore, I had too many of them telling me how I should be racing, how i'm not capable of X yet, how it's too hot outside to run hard, how I race too much etc. just got too annoying. "you're not in X shape so don't try it in a race", "start slower in races", "you go too fast on your intervals", "hitting tempo after a track workout is crazy". Ok who knows, could be true, perhaps not. 99% of people making such comments are "slower", for whatever that's worth.
Seems like I do really well training in my vacuum and then showing up to races, ready for "war".
Kenyans are big on training in groups.. I feel really comfortable training by myself. I think i'll continue to ignore the Kenyans on this one.
