To get into better shape (this approach is a little bit like the "tomorrow diet") i try to use my bike as often as possible. This includes rides to site and home again. But to be honest, although the bikeline is nicely routed alongside the Brielse Meer (similar to the Danube Island), i am missing some mountains here in the Netherlands a lot. However, on a lazy sunday i spotchecked a Mountainbike trail around the Ostvoornse Meer, mostly routed on one of the dikes, continuosly seesawing with almost 2 (!!) meter height difference. Doesn´t matter, that´s better than nothing i thought to myself and gave it a shot.
