we are in the middle of heat wave here, temperatures are around 35 and rising! Not the best weather for riding, but it is better in the mountains. I moved to my parents house (close to the sea) for the summer, so I ride to work at least couple of times a week. It is close to 100 km one way and in the morning (at 6 AM) it is perfect. I mostly take the side roads, because the highway is full of turists and trucks.
I also removed the windshield, back to the normal look.
