You should try going to Knutsford pool. I think it's on Thursdays, during the adults only laned swimming session. There are some blokes there who are obviously there under duress (somehow??) and they get told to do a few lengths by the guy who seems to be in charge of them. So instead of doing lengths properly, some of them walk up and down the pool pretending to swim. I can't tell what they're doing there. I suppose I should ask them. Any ideas?? It's bizarre.
