I've got a fever...
On your deathbed, you won't wish that you'd spent more time at the office. But you will wish that you'd spent more time running. Because if you had, you wouldn't be on your deathbed.
Feeling the growl again
Another potential explanation is that you are using a more limited set of muscles biking vs running. They are going to be sending fatigue signals at a lower HR than when running. They will be screaming for oxygen well before a decently trained runner will run out of the ability to supply it.
My marathon HR is a MISERABLE and unsustainable effort on a bike.

I've never been much of a biker
that might be part of it.
I don't mean anything by that. I'm just thinking that your muscles may be limiting you more than your aerobic engine. If your body was trained to bike like it was to run then maybe you could get closer to the same HR at the same level of effort.
I'm no bike expert but I'm always amazed at the thought of people averaging 25 mph for a ride by themselves (no drafting). I can't do better than 17. A small part of it is the bike maybe. But the large majority of it is my muscles have their limits. And I notice I'm not breathing all that hard... I just can't bike faster.
Thanks again!
According to the Polar people, biking heart rate is 10 beats slower than your running heart rate. Swimming is even lower than that at 15 beats lower.
My biking heart rate spikes very high as I climb our Tennessee hills, but it averages out about 10 beats slower than average running. Same with swimming, but I really have to work hard to get the heart rate up and I cannot sustain it long.
As far as spinning goes ... I don't know. Spinning sucks. Cycling is fun.

Running is a weight bearing activity where as biking is nearly a non weight bearing activity and swimming is even less. Heart rate zones are completely different for all three activities.
In a test of 16 triathletes, scientists at the University of St. Thomas in St. Paul, Minnesota found a 12 beat-per-minute error when they compared the athletes' anaerobic thresholds for biking and running. That means what you think is your threshold while your churn out bike intervals can be drastically different when you go out for a hard run.

Oh roo roooo!
Thanks for this info! I have been cross training 2 days a week, using the stationary bike at the gym and monitoring my HR to make sure I stay in an easy zone. I have been somewhat alarmed to note that my "easy" running zone does not translate into an "easy" biking zone, and now I know why and have some clue as to how to translate.
