Garmin test on stationary bike

Wanted to see what the Garmin would do if I changed the "Sport mode" to Biking, turned the GPS off, and wore the footpod while on the stationary bike at the gym. Not much, turns out:

The red line is my heart rate - if I hadn't been wearing the monitor, this graph wouldn't have made ANY sense. IT looks about right. The blue line is pace, in min/mile - why bike mode would measure pace and not speed, I don't know. The yellow (orange?) line is cadence - measured from the footpod, I guess. That's probably where the problem lies; it wasn't measuring right. I'll have to do a little research into how to get Lumpy to work on the stationary bike...

I decided to get back on the bike a couple days a week for a few reasons - to try to knock some of the running-related pounding off my knees and hips, for one. I hadn't been to the gym for most of the summer, while I was running outside, and was feeling like I needed the overall strength that comes from my (admittedly fairly basic) lifting program. And, I really enjoy doing 45 minutes on the bike, simply because it's extra time I can read. I've got a STACK of books I'm working through right now, and need all the time I can get. Started Katherine Neville's "Fire" this morning, sequel to her classic "The Eight."

45 min. on the bike- that's awesome! Did your legs feel all wobbly afterward because you hadn't biked for a while? I need to bike more, but it's so much more satisfying to see the calories burned in the hundreds when you run, versus the 89 you get for 45 minutes... But it feels like you're working WAY harder than that!

Well, I think that 89 calories was based on the incorrect mileage - the bike itself said like 16 miles and 400-500 calories?
