–Went for a nominal 14.4 mile ride on the canal. Calibrated the odometer and noted it was .075 miles “ahead” in 3 miles. After a whole lot of searching on the web, finally found out how to lower the tire circumference by 2.5% on the bike computer. WRT dementia: I spent the whole ride (and others) believing I’d have to set the circumference higher due to the inflated odometer readings. To be clear: I ride 1 mile, odometer says 1.1 miles, it thinks tires are big. Specifically, tires spin 317 times in 1 mile, odometer says 1.1 miles. By reducing tire size in the odo, it now thinks 317 revolutions is exactly 1 mile. To be absurd and make the point, if I said the tire size was 100mm, the odo would say those same 317 revolutions would take us 50 feet. WRT old age: the ride totally wiped me out. A lot of it was the fact that it heated up early today (91 on the odo around 10:30 AM), but a lot of it is on me of course.
–Went to Bel Air for bagels, dinner (pizza) and dessert.
