Interesting that with the HR monitor attached, the normal workout I do it says around 1,100 calories burnt. On the Strava site, where I keep track of my rides, they log 250 calories burnt. Just weird that they're so far out.

Strava needs a power meter to get calories. For running it uses weight. A power meter is the most accurate. If a power meter isn't used it uses an algorithm similar to what a gym stationary bike will use. From what I've read, Strava doesnt use HR, but I could be wrong.
Garmin uses the New leaf method where you get a vo2 test and enter y,our data as a base line. This is the most accurate. If you don't have a vo2 test done, it then uses the first beat algorithm 1st or 2nd gen depending on the device, and is claimed to be accurate within 10% for 2nd gen and slighty less accurate for 1st gen.
Here's a good write up explaining their methods.
