TT Vs Road bike Heartrate differences?

Stuntman

Bonjourno,

I have recently started uploading my training rides and races from my heartrate watch and I've noticed a pattern, even with full efforts on my TT bike my heart is maxxing out at 6 beats less than on the road bike.

Is there any real reason for this or is it that one of my bike's aren't setup in the right position? Just a note but my road bike feels perfect and the TT is as comfortable as I can get it(how comfortable can you be whilst trying to squeeze every ounce through to your legs?).

Cheers

Grip the pedastal not the toilet seat for maximumm comfort.....

My guess would be position relative to horizontal/vertical. You are flatter on your TT bike and thereby heart rate is lower - even lower for swimming adn higher for road bike - more upright and even more so for running.
There is a chance your road bike position is hampering you in some way - the only way to check would be to measure your power output (as opposed to speed) (did I just write that? )

Its something I've noticed on the turbo - if I sit up the pulse goes up even tho' I maintain same output. Could be similar for you!

Might explain the colour of my shorts

That also explains a lot. Spot on I think, or at least I'll happily assume that's the cause.

Thanks
