It would seem obvious but I'm surprised how my body reacted to a 60 minute ride instead of the normal 30 minute ride. Biggest problem is a tightening of the left calf muscle. Didn't expected that. Did expect and get slower avg speed, more need for water. I was happy avg speed only dropped 1/2 mile. I was planning on going on a 2-3 hr ride tomorrow, but after this morning I'm not sure I'm in good enough shape to do that yet. I went thru one water bottle. I only have two so I think without refills, 2 hours is my max.
Anyway thought I'd share the obvious and see if anyone had any suggestions to prevent problems with calf muscles.
