I haven't forgotten those days, Mary, run ten paces, walk ten paces, all downhill, and I knew I would never get so much better. But then magically, that first time I completed the short circuit around my home, around 2km, much of it uphill, I got home gasping for breath and I knew I would never ever stop.

Shortly after that I could do 5km, then ten became a normal run...completing the marathon, a veritable miracle.

Those were the best days of my life. :)
