For my dad's 60th birthday I would like to take him to a group cycling event somewhere in Europe in the next months. He loves running events, but to give things a twist it could be nice to do something similar by bike. It's not about racing, more just about the experience and cycling as part of an event, ideally mountain biking.
So, do people have tips for group tours or chill, low-key races somewhere in Europe?
Cheers for any tips!
