Thanks for your message. I haven't found anyone to run with, so would be great to meet up. I'm in Walthamstow too, which should make things easier! You're right - so easy not to bother, especially when it's so cold!
I'm doing (well, I've signed up for) a half marathon in March, so would be good to train for that.
If it's easier for you just to email, my address is firstname.lastname@example.org. Hopefully we can sort something out in the not too distant future.
I've been running for a few years, and mainly run off road (canal paths, etc) if possible. Distances between 5 and 12 miles, usually in the Lee Valley, but happy to try other locations. Flexible on days/times.
