• I normally recommend (and use) a flat 6mg/kg for everyone. For ease of use the cheap glucose/dextrose/caffeine pills you can get from Sainsbury's/Boots are fine, don't use Pro Plus as they have sorbitol coating and are way too expensive.

    Caffeinated gum doesn't have enough in it to reach the 6mg/kg for most people so you have to have too much for it to be practical, unless you're doing a long event that needs a dripfeed (long TT, RR, Audax etc.) or an intermittent exercise event like a track omnium or sprint tournament
