Every Day in May - Day 13

The weather today got nice and by the time I went for a late afternoon/early evening ride it was in the low 60's and partly cloudy. I wanted a hilly workout so I chose a route that included Skelp Level Road - which is anything but - level that is. One section got so steep that I had to move up on my saddle and lean into the bars to keep the front wheel on the ground. It was about a 10 minute ride. I need to adjust my bike computer because it is reading about 1-2% too high, at least as compared to IPhone GPS. Here is the bike computer data:

Bike: R
T: 45:45
O: 80.5
M: 39.5
A: 13.4
D: 10.26
