This is their FTP test, which they’ve replaced with 4 dimensional power.
Warmup: Long gradual warmup, ramping up to 210 watts. My heart rate average for this was 126 (first two intervals on my Garmin chart). Power: avg-157, max-242
Test: I started at the same level as last year (240) and felt pretty good so bumped the power up by 10 watts every 4 minutes. Last year I did 5 minute bumps (as suggested by the video), but couldn’t maintain the last interval so dropped back to 250. This year I managed to take each of the power bumps and the trainer chart shows my actual power overshooting slightly most of the time. I was ready to stop at the 20 minutes, but wouldn’t say I was really spent. Heart rate average for the test was 159, which is close to the max I’m comfortable maintaining. Power: avg-259, max-310
So...the lazy heart rate I’ve seen on rides the last couple of months might be as much being stronger as being lazy. The traffic on the path out back puts a limit on how hard you can ride without being a manage. Maybe the long days on my feet at Habitat are making my heart stronger.
Regardless, I feel pretty good about still being able to put out better numbers at my age.
