- Sanders’ Normalized Power for the full 112 miles was an amazing 306 watts and he averaged 40.6kph, or 25.1mph.
- While that is a very big number, it is only 77 percent of his Functional Threshold Power, as shown by his .77 Intensity Factor.
- His Variability Index was 1.02, showing that his power output was very smooth, though his dip in power from the first half to the second means that he could have paced it better.
