This morning my training partner could not ride, we had been talking about being more rigorous about our interval training, for the past month or so we have just been out riding in the mornings, doing some sprints when we felt like it, no HRM. So this morning I decided to use the HRM, I would not have my buddy to push me. What I found was alarming, I was stuck in Z3 hell. Yes I could push myself into Z4, I could stay in Z4 for awhile but there was hell to pay getting into Z5 and no way could I get close to max. I guess I need to strap on the HRM for a few weeks and break out. My speed is real good for this time of year, so that probably means if I can push up to more time at target I can get another 10% and by the time I hit my peak later in the summer I should be logging stronger rides than last year. Now if I can only shed that extra 10 lbs I gained last winter that will be worth yet another 10% due to the rolling terrain. Some how I think that part will be harder than breaking out of Z3 hell.
