Matt and I tested ourselves Wednesday morning on the trainer to get some stats. Unfortunately, my chart doesn’t have the nice “bends” in the curve to tell me what my aerobic and lactate threshold rates are, so I have to kind of guess. My guessing is coming from the way I feel when I ride the bike too, so I don’t think I’m too far off. Another interesting thing to note…the Garmin was way off on all of my zones except Zone 5. Below is the graph for my heart rate and power. As you can see, pretty linear.
So I looked at the graph for my cadence to power. I can find my aerobic threshold in the first bend in this graph. Supposedly, my aerobic threshold would be at 124 HR based upon this first bend you see, but that seemed too low, so I bumped it to the next bend that corresponds with a 135 HR. My lactic threshold will be dependent upon where my breathing became very labored, which was 165.
So based upon a combination of my gut feel and the modified Conconi test, these are my training heart rate zones.
I did a critical power test too to set up high intensity training zones, but I’m not even near being ready for that. Critical power for me is 230 watts. I was able to sustain that for 90 seconds.
