230 Rule: Calculating Mileage Using Heat, Humidity

In South Florida, when the temperature is 90, the humidity is likely to be 90.

I’ve developed the 230 rule: 230 – the temperature – the humidity equals riding miles, give or take 20%.

Hence, 220 – 90 degrees – 90% humidity = 50 miles.

Ever notice how folks on the porch call it a breeze and folks on a bike call it a headwind?
