Last weekend was my first attempt to cycle 100km in one day. For cyclists with racing bikes this is no biggie, but it’s something I hadn’t attempted on my city/trekking bike before. I think I once got close to 100km, on the first day of a bike ride in the Alsace. That day was pretty gruelling as there were lots of hills. This weekend’s 100km went surprisingly smoothly, as it was mostly flat.
