This won't be a lot of help but i find even if i think i want a wee before a race invariably once i get running i forget about it. Noone should take lightly the need to hydrate before running but are you perhaps drinking a bit too much?

PMSL..she wee. !!!
Thats the second time I've heard that topic this week. The whole concept of it sounds sooooo wrong.

No ideas for you Hayley. Just hope it doesn't become too much of an issue for you on race day. Good luck 

Now Craig's caught the affliction just by reading, must be catching. I tend to sing to myself with fingers in ears when it comes to 'ladies issues' as I don't know too much about them and I'm ever so slightly shy, but I'm glad Andy is in touch with his feminine side. 

I'm glad you think i'm a 'new man' in touch with my feminine side, Derek, but I fear my wife would strongly disagree.

For Hayley...and anybody else who may be interested...
