Vince was swimming, not sinking. He's very low in the water, afterwards he was saying he really got into the zone on his final two out of six lengths and was enjoying the water this week. I'm always much higher in the water, I just float more for some reason. It was a dull grey morning with a little drizzle, the water was about 7ºC and I did ten lengths, I felt colder than after yesterdays twelve.
Thanks to Mike from Oregon who sent an exhaustive feature about swim caps from an American magazine, it's given me some ideas of hats to buy. Meanwhile the swimtrek hat is working okay for the past couple of days.
