I am thinking back to when I was a young man attending Arizona State University. I lived in Mesa and did not own a car. From my house to the University was right around 10 miles. I never thought twice about just jumping onto the bike and going. Anytime of day, and day of the year. No helmet (who bothered back then?), no water bottle, no fancy clothes, no fancy shoes, no hydration plan, no Nuun, no shot blocks, etc. Just whatever I had on was fine and I would get a drink of water when I got there. Of course this is nowhere near the OP's 80 mile ride, but it just makes me think about the simple days gone by...
