Hi Louise and Naomi. I'm the manager of PiONEERs running shop in Clapham Old Town (opposite The Sun pub).
Our Tuesday night runs have been going for the last 4 months. We vary the runs from anything from 3 - 10 miles depending what the group feels like doing. We meet here at the shop at 19:15 and set off at 19:30. I email the route out first thing Tuesday morning so you can see what distance we're doing before you turn up.
We will be starting a Thursday evening session very soon which will be taken by Phoenix Personal Trainers. This session will be more specific though, such as interval training, hill running etc. If you are interested in hearing more about what we do please give me a call on 02077203119 or alternatively email me and i can add you to our mailing list. firstname.lastname@example.org
