2 rides for me today. It was blooming hot. We rode to the cafe and back at lunch time. Lots of people wobbling about on the trail, but it's nice and shaded for most of it. Couple of parts with 100m or so unshaded. Then we came home, watched a bit of the Tour, had some tea and walked the dogs, then rode the other third of today's ride, in the evening sun. There is very little shade on that bit of the trail, Hubster didn't feel like climbing today at all as his knee is nagging him. We simply waited until the temperature cooled and had a nice ride, into to some very low cloud over the Camel Estuary (lovely to ride though), to Padstow and back.
Hubs doesn't like riding in the heat as he is only allowed 650ml of fluid a day, so shaded and evening riding is better. Not too much climbing either, he prefers cooler days (think spring and winter) if he's got to do any climbing, as it makes him thirsty.
