I had crazy fun yesterday riding to a lake just down the road from my house and back to my house. It's mostly downhill with a few climbs on the way, and then the opposite coming back up. The total ride was about 11.5 miles (got too dark my wife had to come and get me 1/2 a mile from my house) and the most I've ever done before then was ~5.5 miles.
I had to walk up a few hills that defeated me, and therein lies my question. Should I find somewhere I can pedal constantly (i.e. flat ground with hills that I can handle) or is it okay to challenge myself this early out and have to walk up a few and take a break? I paused Endomondo the couple times a car got behind me and wouldn't pass until I got off the road, and the one time I stopped at the bottom to take a picture.
I'm super proud of yesterday, and I realize I won't do it everyday, but I'd love some help on efficiency in training.
