Firstly, will done to
@M18CTID. Stick with it, and try and get some outdoor runs in to compliment your treadmill running. If you can, when the time is right, join in with a parkrun. The sense of being in a running community is very encouraging. It's a great aid to weight loss too, but couple it with some sensible and disciplined dieting.
Now, one of my goals for this year was to run a half marathon (about 22k). I managed 19k once, and I regularly run 7, 10, 12 kilometres. Well, this afternoon I went out on a run, and completed 14 miles in 2 hours and 25 minutes - slightly more than a half marathon. I'm really, really tired now, but buzzing at having achieved one of my goals.
