I cheat.
Commute 15 miles round trip to along distance bike ride 5 to 6 days a week..
Most of my rides are 85 miles
223 lbs to start, Now 188 lbs.
So what makes the commute different from the bike ride.
(1) meet group at a given time.
(2) traffic, school zones, fast riding on a no shoulder roads. freeway over pass.
Rush hour traffic going and coming.
(3) I get horned and yells everyday
My wife of 48 yrs says, I am Nuts. That the other riders are nuttier then me.
