I’ve been using trainerroad for the 2nd winter now, and I’ve run into issues. After a 2 week break at xmas, I did the ramp test and my Ftp dropped from 208 to 180. I repeated 1 week later and same result.
Ramp test history
Dec 13 - 208 3.2w/kg
Nov 22- 203 3.0w/kg
Sept 7 - 208 3.0w/kg
I was riding 4-5 times a week, polarized plan with approx avg TSS of 232 per week since Sept 1. At xmas, I received the Favero Assioma duo pedals to replace my spds. I ride the Stac Zero Powermeter trainer, not a smart trainer. The power readouts seem very close ±1% when used at same time. I also have a minor SI joint issue i’ve been dealing with for 4 months while training. My diet for 4 months has remained low carb.
What is the most likely cause of ftp drop? The new pedals seem to have a wider stance width than the spd’s.
Stats - 44yo Max recorded HR - 190
On Dec 13 ramp test, I did 5:45 of work above 170 bpm.
Last night Ramp test, I only managed 1min 33 sec of work above 170 bpm before I had to stop.
Can different pedals work different muscles to the point where I couldn’t raise HR any more before the weak link gave out?
Any other thoughts, with solutions greatly appreciated.
