Eek Smitch, that sounds like the starting point of an investment! You'll be buying a cossie next.
Having been for an ickle run this morning before the cloud burned off (good idea), I took the family out, plus hanger on children, to Cheltenham Lido this afternoon.
Wife looks after smallest, and I did 400m in 11 minutes. SLightly less slow than last time, but still no more than 25m crawl.
Then I look after minion, so she can knock out 800m.
One of the peeps in the lane I was using wasn't trying, but still carved out 400m in 6 minutes. That is why crawl is for all.
