Last weekend, I participated in the well-organised and fun walk in Brussels, called Urban Trail.
It was not just an ordinary walk or indeed run, but a 10 km trail through the very central of Brussels, walking (or rather zigzagging) not only through the streets of the city, but through museums, concert halls, bars, schools, the train station and even down the sewage we went! Lots and lots of walking up and down stairs also - that was the surprise of the day.
Here you have the first set of highlights from the walk.
