 fed sodium bicarbonate (baking soda) to combat a lactic acidosis that wasn't 
 there and made their horses even more alkalotic.

Yes. Very important concept that many, I think, don't understand yet. Little 
sprints uphill during a ride are probably quite beneficial--lactate is your 
friend in this regard--becomes another readily available substrate from a 
source (FT muscle cells) that will otherwise go essentially unused.
