Beep, Beep, always good to curb your enthusiasm .Yeah, it's pretty rough, setting the limits on the HRM and then forgetting about anything but running ... somehow I manage.
At least you allow yourself the guilty pleasure of hill intervals and fartleks from time to time .
Anyway, apologies for the trolling, just couldn't resist The Prisoner clip quip, please carry on. A lot of you guys have had success with this approach, and I can't even run anymore, so I'm out.
