Right now I'm trying to figure out
when he gets sluggish 10 or 15 miles into
a ride on a summerafternoon in
the high 90s or more, if it's
because he's hot, tired, orlazy --
i.e., how insistent I should be about speeding him back up. Sortingout the factors is complex, but I think cool
weather will help give me theanswer.
