I order Gu gels and Clif Bars from Wiggle every once in a while.How do you go about getting your drinks and gels etc?
The Gels you buy at the conbini are useless and basically a placebo. Yes they have some nutritional value but compare them to other "Brand" sports gels and you'll get the idea.Slightly strange question in the land of the combini, but FWIW...
Gels are available in any large-ish drug store, at least in the suburbs. Same for sports bars, although the brands/contents are different. Combinis often (but not always) have gels/bars, too, but if I'm there anyway I'd usually get an onigiri or something instead.
For sports drinks, Pocari Sweat/Aquarius are ubiquitous, and presumably contain the salt/water/sugar needed (not being an expert).
