She claimed to be incapable of more than that until her first bike race which had an uphill start and to stay with the field she hit 163 bpm. So what is her max heart rate? 175 or 163? That is a big difference.
Running uses a many more muscles than riding. Perhaps that is why my coach had me get out of the saddle at the end of the test interval when I could not keep going seated. Because your wife hit 163 in a bike race that doesn't mean that was her MHR, it was her max HR for that race. I think if I hit a HR within 5 beats of my MHR in a race for longer than 15 seconds the field would get away.
