In the chart below there are two groups of lines: Red for speed and Orange for time. The red jagged line spiking up and down is the average speed for the 3.8 miles of Glendora Mountain Road used for the San Dimas Stage Race. The straighter red line averages the averages of speed sloping upward to show that the average speed is getting faster which is good. The orange jagged line is the average time. The straighter orange line averages the averages of time and is sloping downward indicating the time is getting shorter again good. Of course I have chosen values on the x-axis to show a difference.
