Considering that this is supposed to be a 'rest' week I felt very tired for today's swim. For the first few lengths I wondered if I'd manage to do thirty at all but with a bit of determination I reached 38 lengths. I was even slower than usual.
In terms of technique I made quite an effort to exhale for much of the stroke although I find this difficult, especially as I tire.
From general niggles and DOMS sensations I think that I'm suffering from Thursday's rather intense circuits class. Today really must be a rest from now on.
