I did the standard base and finish line rides.
Short climb was basically exactly the same
Sprint was more or less exactly the same
Both were within hundredths of a second and ± 3w of each attempt.
The longer climb up the volcano was 10 seconds or so quicker on the finish line ride.
Although the results on short efforts don’t reflect much change I feel a bit better in myself working around threshold after health issues early in the year saw my power drop and zwift power rating fell from B to D, I’m now back at B after these rides have given me decent 20min efforts.
