True, a fit rider could do it in such a time with favorable wind conditions.

I am by no means a good rider, but on Saturday I took my bike back for the first ride of the season.

I put a new battery on my computer, so it was all zeroed.

I just did a short ride Zurich-Horgen-Zürich to dust myself off, when I started I was feeling heavy and slow, and my back not fit enough to bend down. My speedometer showed ~22 Kmh at the beginning, but at some point I reached ~40kmh somewhere in Thalwil.

At the end the computer showed average speed of 28Kmh which is not bad for an old and cranky guy on his first ride after the winter

At that pace the short lake tour ( through the Rapperswil bridge ) can be done in around 2:30

The next day on sunday, I did my first mountain short ride Zürich-Horgenberg-Zürich.

I wanted to go to work by bike this week ( Zürich-Samstagern so 30Km one way with 900 mts elevation ), but I have been lazy and the temperature was somewhat low.

I'll wait until we are over 12°C before doing that. It takes me usually 1:20 so an average speed of ~24Kmh. ( coming down is faster so ~45 minutes )

I am quite happy with these times, and for sure I am by no means a fit rider on the dakman, hillseeker league, but this keeps me happy and fit.
