I'm working to get on the first level.
Training 10-12 hours per week is vastly improving my physical and mental health, so I know I'll pick a 'next level" when this one is finished. Level 1: gran fondo with 8,300' of climbing on May 21.
I started cycling in Nov '21 and was in terrible shape after 40 years of sloth. My CV fitness was "off the charts", but off to the lower left. In Nov '22 I started a 6 month GF plan using Training Peaks, and still amazed at how well tuned it is to my level of fitness. There's no doubt about where I'm strong and where I need to improve; strong on the 1 hour interval rides, weak on the 4 hour rides with long Z3 pulls.
After a career in technology and sales, I like how there's no BS or workarounds to get to the next level.
