The running club in Loughborough is Charnwood AC - it's based at the university and, as the name says, is an athletics club and has track and field sessions as well as road / cross country. There are a number of other running clubs in that locality - Barrow Runners and a club in Wymeswold. Going closer towards Leicester, there's Birstall, Beaumont, Wigston, Roadhoggs. Have a look at the LRRL (Leicestershire Road Running League) website - that will have more names and then you can look at individual websites and see whether any appeals. One of those is my club, but I won't say which as that might put you off!!
