Just got back from a trek in the Black Mountains with Owen. It was freezing up top, the lake was totally frozen. Was a hard climb but got extra energy from a sausage baguette and a box of Christmas chocolate liqueurs which Owen had sneaked up in his bag.
Stopped off at one of my favorite dipping pools on the Tawe on the way back, was running well with snow melt, water was 4 degrees, the coldest I've been in yet. Couldn't move my fingers afterwards, putting socks on with no fingers is impossible!!
