I did a mile today. I didn't really time it, but I know I was swimming faster as I got more tired, and found myself stopping for a 30 second rest after every ten lengths. And tomorrow I am going to put my head in a sink of cold water and practise breathing out, and go for a longish run.
I now need to adjust my plan, to make it a standard triathlon training plan, as well as a marathon one. It's 6 weeks until the triathlon, and 10 until the marathon.
I am also going to knit a big moth.
That's rather exciting. It will be bigger and happier looking than this one.
