What I am trying to say is that when you are sucking wind and your legs feel like rubber they don't work that well. They have less bounce, and you loose some coordination. That is usually when bad things happen. Its not that much different than basketball players or hockey players in the last 10 minutes of a game or a downhill skier doing the last run on a hard day of skiing when everything is burning and then they put their foot in the wrong place or wrong angle and a body part gives.

Paulo, I may have less book knowledge, but when it comes to the real world...well, I'll just leave it at that. I'd rather that this thread be an exchange of information for people who want to discuss their experiences than a pissing contest between guys trying to stroke their egos throwing studies and book knowledge at one another and being critical of one another's knowledge, thereby shutting down the free exchange of ideas

Thanks.
