Last night I had a good swim in the pool.
It was just such a relief because ever since I started swimming in cold water my pool swims have pretty much sucked. Especially the day after an ocean swim, my muscles felt sore and my limbs just generally heavy.
I thought the vasoconstriction was the cause of the sore muscles but after being in the ocean on Saturday, Sunday morning's swim felt great, and last night's was even better. So either my body is truly acclimating, or something else was contributing to my crappy feeling in the pool.
I look forward to Wednesday night to see if it continues.
