RWTD,

sounds like you track carbos/glycemic index, the way I was trying to introduce a possible balance or scale torward the introduction of fat and or protein even before post event recovery....

The "top off" scenario I'm referring to is much like TDF riders fueling and drinking between any possible "maximal" efforts that may be presented.
(not pre-event total loading -- that's a given)

However, in a TT or iron-man like event, everything is kind of "metered In" so you don't end up with full bladder..or risking possible digestion-induced, "heavy legs"

In any case, I'm going to try some protein-containing products for end-of-ride use. Sometimes I already do, low-fat chocolate milk!

Haven't done the accelerade thing, was thinking, sustained energy....

Thanks for the comments.
