oldbloke's mutterings

Yesterday I checked with the lifeguard how long the pool I've been using is. Because it's half of a 50mtr pool which has a divider that comes up when they want to split it. And the /other/ half is 25mtr, the half I've been using is only 23. So I didn't do a kilometre on Monday and Wednesday, or a hllf kilometre last night. No, 40 lengths leaves you 80 metres short. I did do 42 lengths on Wednesday, so not so far off. Can't remember about Monday. Ah well. I must work out how many lengths for a mile, though I won't be ready for that for a bit yet.
