(1) Bicycle ride from home all the way down to the James River along Riverside Drive and back: 14-something miles at an avg 15 mph on my Fuji road bike === 843 calories burned.
(2) Jogging 4 miles in under a 10 min/mile pace === 819 calories burned.

Wow... A little over triple the distance, obviously way faster (almost double the speed), and the amount of calories burned is pretty close to each other. One is scenic and not really that tiring. The other is a harder, tougher, workout, but more harder on the body. What was I thinking? Anyone else go running?
P.S... As I wrote on Facebook yesterday when I got back home:
I'm sorry, but I think your cycling caloric estimate is way too high. Here is the data from a recent one hour threshold workout:
1:00:01(1:00:07)
Distance 22.2 mi
TSS102
Work 959 kJ
IF 1.01
NP 273 W
VI 1.03
Assuming a 25% efficiency, you can use KJ as a proxy for KCal. 959 / 22.2 = 43.2
Average speed on that ride was 22.2 mph.
