Howling wind and the threat of rain that never came.
70km 1050 gain (350x3), average speed 25.
Power bars at 30min intervals made a big difference. The 24 helps also. I did not feel tired at the end but i am geting a little back pain. i don't know if its the climbing or my position on the bike. I will avoid steep climbs and high gears for the rest of the week.
