I went to my new masters club and it was really good. There were 5 lanes and I was put in lane 3, which was just about ok for me. I was the slowest in the lane, but it stretched me, so must have done good and I didn't hold anyone up.
Found the session really hard as I'm not used to that kind of swimming. I can't do butterfly and my back stroke is crap and as for diving.....
Anyway, I think I'll go back again even though it's a bit late for me to want to train. I also think I need to swim more than once a week not to struggle with the session, but it's the time!
Oh, also an interesting comment on my swim style was that my stroke was fine, but I bring my head out of the water too much when taking a breath-but I need to breathe!
