I just finished up Trad Base mid volume and entering SSB 1 mid volume. I had a significant break from riding (3 months) due to surgery. Road consistently for fun for 4 weeks then entered into Trad Base at the beginning of Sept. My initial Ramp Test had my FTP at 330. (Down from high of 360 in late 2017). I just took another Ramp FTP test this morning and felt crappy. Got a miserable result of 302. Not sure if it is fatigue but wondering if I should scrap it, keep my previous test (4 to 5 weeks old) and retest next week. Anyone have advice in this situation?
Some additional context is my diet changed (now vegan) 5 weeks ago. This was not a huge change as I was pretty close to being plant based before the full change. I believe my calories, macro nutrient mix and nutrient density are all good, but I am not militant about tracking. Could the change have such a dramatic impact on my testing or is this more likely a not properly rested issue? Just looking for thoughts.
