Well. Been swimming. Was pushing it fairly hard. Intended to swim 600m but 10 lengths in my quads were burning and I was so out of breath it prompted a total stranger to ask me if I was ok.
My response was a rather out of breath “f**cking hell” as I tried to stretch out my quads.
This all worries me. How can I have got so drastically unfit? Gutted beyond belief. It is going to take a fair bit of work to get anywhere vaguely fit
