Now I know these aren't really part of triathlons and most pool based swims don't allow them. However as I swim on a daily basis and think I'm a very able swimmer this is the last thing that I really would like to do. So do people have any tips on how to do them? I occasionally get the lane to myself and sometimes only a few people in the pool and have practised floundering around doing them. Is it just a case of keep practising or are there any tips people can offer?
