I graduated some day last June. I did most of my runs along the lake starting after a 1 km walk from my house, simply because I do not like the idea of taking the car to go somewhere flat. * The route is slightly uphill for 1 mile, then I turn around and fly down Ideal for negative splits - not that I knew what they were when I started.
Today, after picking the worst moment of the day to get out, chilly wind and freezing shower, the temperature dropped to 5˚C from 12˚! I started a short and easy run along the same route - last year I was struggling to finish the 30 minutes, managing about 2.5 k - that is slower than a brisk walk - and feeling wrecked at the end. I am still slow, and wasn't putting any particular effort in today (as apparently one is supposed to taper before a race), but in those 30 minutes I did 3.6 k, and I feel I could go and do it again right now...
All this to say, to all of you that have just started, or are starting again, or thinking about doing it: it is a fantastic program, running makes you feel great, and the slightly insane people on here will support you all the way - you'll do it!
* real flat around here can be found only at the GAA pitch, and on a treadmill....
