Sub 10

In a masochistic way, I've been looking forward to this day - the day when the water temperature dropped below 10 degrees. Today the temperature was 9.75 degrees. Some Lidos close when the temperature gets this cold, but not Brockwell Lido!

When I checked the web for useful tips on how to survive in cold water, I discovered that swimming increases heat loss and can shorten survival time by more than 50%, cold water robs the body's heat 32 times faster than cold air, 0-11 degrees is regarded as freezing, and few people can swim a mile in water that's only 10 degrees.

So, my swim today was quite an achievement.

I can't wait to see how cold the water is tomorrow.
