To plan my 2022 season, I am tentatively scheduling plans on TrainingPeaks and looking at my expected fitness level. Thanks to a variety of FasCat plans, my fitness level is currently the highest it’s ever been. However, I noticed that after the planned completion the 18 Week Sweet Spot plan in spring 2022, my fitness is actually expected to be slightly lower than it is now.
My core question is: Can I supplement the Basic plan with a week or two of longer endurance and sweet spot rides to boost my fitness? On a recent podcast, Frank discussed using a training block week 2-3 weeks ahead of a gravel race to boost your fitness. Wondering if the same principle applies to base fitness. Using the Intermediate plan would be a bit of a strain on my family obligations, but I have the flexibility to take a couple days or week off work and get in some longer rides while on the Basic plan.
Thoughts? Thanks in advance.
