Hi,
I've been doing Hunter Allen's prebuilt Threshold Improvement program for about a month now, and I did 6x2min AC (L6) intervals according to the program.
Currently I don't have an indoor trainer so I chose a short steepish hill near my home. The slope is steepest right after the start, and gets a little easier, then there is a nearly flat section around three quarters up the hill. You can see it in my power curve below, where the power output drops sharply no matter how hard I try to compensate for the decrease in the grade by shifting up and going harder.

My target average power for this session was 286watts (130% of 220watts), and power values for the six intervals above are:
min max ave (NP)
1st: 150 462 319 (330) <- started out too hard
2nd: 160 409 294 (286)
3rd: 160 417 292 (283)
4th: 127 388 289 (285) <- power drop during the flat section went uncheked
5th: 202 429 292 (283) <- tried to compensate for the flat section
6th: 188 381 286 (281) <- same as 5th
I can see my average for the interval dropping significantly when I reach this section of the road although I put my PowerTap computer in average power mode, so I have to go much harder for the last 5-10 seconds to stay in my target.
My question is: with power momentarily dropping down to L4 or even L3 levels during the work period, can these be considered 2min L6 intervals? Or should they be considered shorter intervals at higher training levels?
Should I look for another hill with more consistent grade? (not a "get a trainer" advice, please 😄 I'm saving for it and eventually get one, hopefully)
TIA,
Ken
