Hi, I've had a mountain bike for a few years, but seeing as it's getting quite old and very broken, I was thinking about buying a road bike instead. I'd probably be riding it two or three times a week at a distance of around 10-30 miles (I have no concept of distance, sorry) and I live in a very hilly area. My budget is about £1000. I'm 5 foot 11 inches if it helps.Thanks
