For context, I’m not competing / serious, and in Northern hemisphere so am at lowest fitness in December and highest mid-year. Here’s a summary with a bit of additional context to my training approach and loads (with the usual caveat that it’s not ideal to look only at TP without HIE, but it’s the easiest to see from the progression charts…):
Really started Xert End 2018 ca. 270w TP with TL of 15… (prior to that I’d done one season of structure with TR and improved significantly, but that was also coming off a zero baseline due to injury so hard to compare…) then with training --------> Peak 2019 300w TP with TL of 39… mostly following Xert though with less rigour for intervals in summer
End 2019 ca. 290w TP with TL of 24 --------> Peak 2020 330w TP with TL of 57 … mostly following Xert with a little bias to lower intensity (again with less rigour for intervals in summer)
End 2020 ca. 320w TP with TL of 40 ---------> Peak 2021 345w TP with TL of 57… following much more polarisation… i.e. much lower intensity endurance than Xert’s typical endurance workout (which also means more hours for the same TL). Part of the bump in TP was offset by reduction in HIE that year, and power at lower heart rates improved significantly.
Now I’m way back down after a break and easy end to the year. Starting to train a bit more now. Not sure if I reached my limit given available hours last year, but time will tell. May try a more pyramidal rather than polarised approach next year out of interest
As you can see, I started by largely following Xert but over time have focused more on lower intensity endurance rides vs what Xert prescribes. Not because of any issues I had, just out of curiosity and based on research suggesting the value of polarising training. I’d also suggest that part of the improvement year to year is also from a) consistency within a week and from week to week and b) training through winter, rather than having very long periods completely off the bike. Would say Xert has helped on that journey hence still with them
