I bought my first bike (a Sears Free Spirit 10-speed) on 9 August 1981, when I was 24 years old. Today is the 35th anniversary of this purchase. Since then (on a total of five bikes), I have pedaled 88,234.5 miles, which is an average of 2,520.9 miles per year, 6.90 miles per day, and 48.3 miles per week. Today's ride of 34.2 miles gives me 3,773.4 miles for 2016. The heat index was 104º when I returned to my house. Having ridden in Tucson and Dallas/Fort Worth for 33 years (since August 1983), I'm used to the heat. I hardly notice it.
Addendum: I've pedaled 5,902.3 miles in the past year (counting the leap day in February), which is an average of 16.1 miles per day and 112.8 miles per week.
