It's built from ~1000 road bike rides since 1998. I pulled all my MTB rides out of my data since they really mess it up. The line is a 5-point moving average of average MPH for all those rides.

X axis is time, from July 1998 to 15 minutes ago. Y is aveage MPH

Looking at the trend, tell me what conclusions you draw about my fitness, my ability and my progress.
