The Effect of Distance on Average Speed

In 2021 on a geared bike, Jeff found that you spent 52% of your time riding below 10,000 feet. 35% of your writing was done between 10 and 11,000 feet; the rest about 13% of his time was spent above 11,000ft. By comparison, a fair bit of the train below 10,00 feet is actually fairly flat. So per mile average speed is actually higher there.
