In the previous FRR (5 weeks ago?) I got a few results very close to my FTP, despite being fatigued, so already back then thought my current number must be off. After that the only races I did was the ZRL and the nature of the courses didn't really push me - the TTT came close though, I finished that a few watts below FTP and felt I had soooo much left in the tank. The race yesterday was just a perfect storm really - hard pace on a flat course so I was desperate to hold on to the blob. Nearly lost the wheels 5-6 times and had to surge, slingshot through the blob, settle down, push again. So 20 min power was best ever (263W) but 30 & 40 min. was as well (257W & 253W respectively).
Was definitely worth it - finished the stage in 6th in my category, despite only 66th result on the final hill (that started around 41 minutes in).
Weight has very much settled down now, Andy. Been 67.5kg or there about for 4 or 5 months. That gives me a BMI of 23.6 so I'm not thin by any stretch of imagination
Gain through fitness vs weight loss:
06/11/2021: First Zwift race - that you fan viewed! 20 min. at 208W at 73kg
28/11/2022: Latest Zwift race. 20 min. at 263W at 67.5kg
So an increase in 20 min. W/kg from 2.85 to 3.90. 1.05W improvement overall, 0.35W from lost fat so smack down 1/3. Remaining 2/3 is power increase. I did one structured training session throughout all that time - didn't like it.
