Very cool morning, especially wearing cycling shorts but I survived it. 4C/39F, but clear and sunny as I ended up leaving a bit later than normal. It was especially cool on the last stretch as I headed down the hill to the level of the lake, there must have been dampness in the air that was making it feel cooler. I wore cycling shorts and short wool socks but my tops were: thin merino baselayer, long-sleeved jersey, wind-proof gillet/vest and long fingered gloves on my hands and a Buff under my helmet.
