Follow-up. Things got better and I started bicycling harder/more frequent/longer rides. Started drinking a bit more this week (Vodka Lemonade, OJ) and I started getting some of that tightness/cramping back in my legs. So need to dial that way back and cut out the Vodka!
I don't particularly care for Vodka mind you but is a treat in the Lemonade and OJ when it's hot out. I can go without it now I see it causing some muscle tightness again.
