Thanks Sarah - very interesting read. There are some good points here that I wasnt aware of.
I hadn't realised that dehydration could be a factor & know I don't take on enough water / fluids before training or racing as I'm worried about the 'sloshing' effect. I'll definitely have to address this in future.
Also you mention that hot drinks can have an effect, but I also find very cold drinks from the fridge can cause a dodgystomach. Dont touch fizzy drinks with a bargepole for the same reasons!
Often wish I'd been good at another sport which involved less impact....running really seems to exacerbate stomach problems.
After 16 years of hiding ongoing stomach problems to my running club and training partners (due to embarrassment) I finally 'fessed up' last night...thought I should explain why I have to cut so many training sessions and races short, whilst sprinting for the nearest facilities!
