Higher Heart Rate When Running With Partner??

Hi ladies!

I have noticed a strange and annoying phenomenon, and I'd like to know if others feel the same way.

When I run by myself I have a lot of control on my heart rate, and can keep it, say, between 165 and 170 on flats (my max is 200-something). However, if I'm running the same course with my running partner, I run at the same pace most of the time, yet my heart shoots above 175 quickly and just stays there, and goes back there after taking walking breaks (on 10K+ runs). She and I are similar runners, I'm perhaps a little bit faster, especially going up hills (she's faster on the downhills),

The pace is very similar but the time is usually different: if I run with her it's more likely to be at 7am, while I run by myself towards the end of the day. Could this be the cause? Are we maybe taking a faster start and my body reacts to that negatively? Any ideas?

I find this a little annoying because those 5 to 10 beats per minute make a difference at the end of my workout. Any clues?

I am sure more experienced runners will have better answers. For me, I usually run at night. I run the same route and when I run in the evenings I keep everything nice and even. When my routine must deviate, due to life, and I must run in the morning, I notice everything is slightly off kilter. Could be something to do with body temp, HR, and balance during various parts of the day?

I find that to be true for me, too. I think the problem for me is that when I'm running with a group, or another person, we talk. Talking causes my HR to be at least 5-10 beats more per min. than when I'm alone (or at least quiet). I don't know why (working harder to keep talking while not focusing on breathing?). Also, the time of day could certainly be a factor. I used to run at 5 am, but have found that I'm much more "warmed up" after a day at work, and have a better run in the evening when I've gone through an entire day (even tho I may be more tired from the day's work).

Strange, huh? I wonder if anyone else has any concrete reasoning for this.
