Lausanne and back

I am increasing the biking distance gradually, preparing for our two-day around-the-lake trip in July. Today I cycled to the other end of Lausanne and back without stopping. It was around 44 km, half of the daily distance planned for the trip, feels encouraging. Even though at the end it was getting more and more uncomfortable sitting on the saddle. As Eric Cartman put it, my behind was killing me. Seriously guys.
Actually I stopped once, to take pictures of the private mini-train going up to the vineyards. It is a funny thing, a plastic chair fastened to some pieces of metal, powered by a small engine.
