I am sure there will be a lot of discussion about this here on the forum, and i hope the comments stay respectful unlike some of the things that have been said from the tabloids forum. The Independent in particular, had some rather nasty comments online. Not worth repeating.
Its sad that she died, and having not known her, or anything about her, all i can say is, just let her be, let her rest in peace. Whether she had done too much training, not enough training, ran with a dodgy heart, or whatever caused her death tragicaly, just let her rest in peace. Just maybe there might be people on here, who did know her, and would want conversation to be respectful. There will be anti-running league people like Terence said above, and people that think the race should be changed, but let them argue it out, since it wont amount to nothing. Nothing else is there to say.
