Just been for a successful swim down at ye olde Abingtonian pool. First 20 lengths more or less continuous (just touching down and kicking off from the side at each end). Then another 10 – some of which were double lenghs where I just continued to swim round and back. Then, as a bit of a surprise to me even, the last 10 were divided into 6 and 4 lengths a-piece, and were actually genuinely continuous!! 🙂
