[QUOTE 4854458, member: 259"]I don't use reusable bottles on the bike as the whole idea is minging. I use water bottles from the shop and I top them up during the ride. And then I chuck them in the recycling bin.[/QUOTE]

Isn't that a very quick incubation period for a waterborne illness? (Not that I know shoot about the waterborne illnesses of the British Isles).

(believed to be the cause because it was about the only thing I'd consumed different to my lovely wife who was unaffected and very kind to me for the rest of that trip).
