My 'Leppin-Squeezy-story' is a classic what-not-to-do in terms of marathon prep (tho i got away with it...)
At the Expo, after I'd picked up my race number (this was '99), I was so flush with enthusiasm that I started scanning the merchandise stalls for bargains. Needless to say I found an industrial size box of Leppin sachets in 876 amazing flavours for about 84p. I bought them and used them for the first time (yes, FOR THE FIRST TIME) during the marathon.
A bad, bad thing to have done. I know.
But - apart from some flavours tasting like battery acid - they did the trick pretty well.
Like the taste of jeely babies better...mmmmmmmmmmmm
