Caveat Xysticus

Did a short four-miler with my brother down in Tampa at an easy pace. This city fits the definition of pancake flat. When I used to live here many moons ago, I would use bridges for hill repeats.

I have proof of how flat it is. At first glance, the graph below from today's run looks pretty impressive. However, a closer look along the Y-axis reveals otherwise (click on the image to enlarge):

Paved roads. 

Flat.
