Aaholmes – This won’t answer many of your questions but here’s some of my experience using the power meter.

 

I did not perform the FTP test as I already have a fairly well established AnT and did not feel as though I needed the metric currently. This will change when I’m performing my next AnT test.

For Z1 and Z2 I watched my Z1 and Z2 HR and saw what range of wattage I was getting. Mine seemed to fluctuate about 15 – 20 watts while hovering between +/- 2 BPM of my AeT.

What I’ve found most interesting is to watch the decoupling of AeT wattage from AeT HR on long runs. As I fatigue I notice that my RPE and wattage will remain at AeT levels while my AeT HR can drop to 10 BPM lower! I’m not sure if I’m interpreting the data correctly but I take this decoupling to show the fallibility of the HR based training. If I was trying to maintain my AeT HR I could possibly be overworking myself. This may also highlight the importance of monitoring RPE.

I’ve seen a difference in wattage when I change pack weight and appreciate that as well, I think it’s an accurate adjustment. I haven’t tried using the run power model for skimo, but I imagine I’ll figure out additional weight because of the approx 3 lbs per foot. Will this mean additional 15lbs on my back? I’m not sure. I know the Vo2 numbers per Lb on foot but not precise on weight on back.

What have you noticed with your usage?
