7Rider, I have a high HR, too. It's always higher than everyone else's, when I am riding or running. It's low when resting, though.
I stopped wearing my HR monitor because of this.
I haven't run in 2 weeks, because I've been riding so much, since it got warm out. Getting ready to go out and ride and now, after reading this thread, I want to go on a trail run.
We shall see. I'll never be a runner on this schedule (that, and the fact I am slower than slow).
