Today I got up and — despite the chill and the occasionally-icy pavements — I did my mile. My time was 11:33, not good, but at least I did the mile. Clearly this is a plateau for me; I’ve made up the easy conditioning, and here on will be the hard, frustrating, incremental gains that may buy me a few seconds at a time. I’m hoping that the weather begins to favour me also; my gasping is aggravated by the cold air and the chill winds. I do worry a bit about my lungs, but the only thing for it is to keep exercising.
