Join a local running club!
They are not all full of elitist, super-fast racing snakes. They are made up or ordinary runners, some faster, some slower, who like to run with other people.
It's way easier to find someone to run with, and a lot safer than taking up with someone who responds (if anyone responds) on the internet.
Most clubs will be happy to let you come along for a few sessions to see if you like them, so you don't have to join up without meeting them.
To find a club near you, either google "running club" and the name of your town, or look on the England Athletics website (or Scottish or Welsh as appropriate).
