I take my daughters dog with me now most of the time, when i go up to the mountain walk, i let her off her lead, where she can then stretch her legs and run about, so i then have to run a bit to keep up with her, so along with the 2 hour walks that does me, Wallace park is good for her too for running about, I am starting back to the 5 aside football on thursday night, been out for 8 weeks now , we might aswell enjoy this spell of good weather we are getting at the minute in N-Ireland, as we know from past experiences, it dosent last long. Siilver you will see and feel a big difference in yourself by the time September comes, i also felt that going for a run in the early Autumn evenings felt far better and it seems you can go a bit further and faster, probaly the cooler air coming in at that time of the year.
