Have you tried putting in some short sprints once a week on a short run and upper body work a few times a week, try stopping at every bench when on a run and do a few dips or press ups, start easy by staying on your knees.
Totally shake up your training to confuse your body, it might have got used to your current regime.
HRM is a goodd incentive for me...boys and toys!!
But do keep going.
