You get the idea from everyone else. We live close to Hallam collegiate campus. Five min ride to Endcliffe park (if that) and then off road all the way to the Peak District by MTB. Some cracking road riding too, although some of the bigger roads (Snake Pass especially) need to be out very early to avoid traffic (6am and before in summer).
Some cracking road and off road riding. Easy drive to Manchester airport, London under 2 hours by train, direct trains to Edinburgh/Glasgow/South West.
Not really anything to dislike, apart from lack of big city life as others have said (would argue that’s a plus!)
Fewer high end restaurants than Leeds/Manchester/Brum if you like that kind of thing.
