Today was fucking cold. The gym where I train has picked the coldest week of the year to cut off the hot water so their new system can be installed. That means NO showers - not even cold showers - because the showers function on a smartarse system that shuts off the water if the "correct" mix of hot and cold isn't coming through.
BRRRRR.
For those interested in figures, the minimum overnight was 4.7C, and the maximum, if you can call it that, was 14.5C.
