As far as I can remember, Ive once been in actual trouble of hypo, and another time it was just a nasty but not serious spout of coldness.

The first time was when I recce’d the Coniston FR route in pouring rain and cold cloud one October morning in about 2009 or 10.
I lost the path up Weatherlam and ended up in a crop of huge rocks. I didn’t know where the hell I was and I was desperately cold. My OMM smock was soaked both inside and out, and my gloves were saturated. I sat down behind a rock to get the map and compass out, and had to force myself to get up and move. I tried to carry on, but bailed after Swirl How and just dropped straight down to Levers Water. Thankfully by the time I was at the tarn I was out of the cloud and I could warm up. Certainly a reality check that you don’t mess with the weather!
The second time was after Noonstone when it was the English Championship race the other year. Id fallen in every bog going and was soaked. I had hitched a lift with a few clubmates who were a while finishing after me and I was stood around getting cold. By the time the car was opened, I couldn’t use my hands and couldn’t get undressed out of my wet clothes. I was given a pair of dry gloves and gradually my hands came back.

Since then, Ive always taken a pair of gloves with me to wear after a race or training run, just incase.
