When I started doing the morning (breakfast) rides with the retired members of the club I belong to, I thought it was kind of neat..
Ride 20 miles and stop for a coffee and bagle break then ride back to the start.
Then I started doing a tuesday morning ride with a rider who didn't like stopping for more than the power bar and water.
"What" I discovered was: I stopped having the leg cramping and muscle fatigue I was having after those 20 min./half hour 'coffee breaks'.
I got more out of the ride as well (conditioning wise)
So I ask: Ride Breaks over 5 min or so..yea or nay for the rest of you folks?
