Just to give an update....I rode back home from work yesterday and it was a 15 mile ride back. So a total of 25 miles round trip. On the way home my quads were tired or felt tired because of the lactic acid build up from the morning ride, I would guess. After about 5 miles into the ride, my quads started to feel pretty good. This route back home was the first time I rode this route and it has some rolling hills on it. I had one hill that was a beast.
Getting up this morning, I felt like I would not be able to ride today. I hadn't planned on it anyway, but just checking anyway. My guess that doing two rides a week for a little while is about all I'm going to be able to do until my stamina gets better and I get better conditioned.
In any case, it was definitely nice to be able to ride to work and back on the bike. I can see how this could become addictive.
You all have a great ride today
