Training camps are essential, and I did the same — one reason to thank COVID??? Anyway, progression without too much detail was from 360TSS/week in February and 460TSS/week in March pre-lockdown to 740/week in April and 780/week in May. That does not count the rest week every fourth week at 67% peak TSS volume. For reference, I started training with an FTP rest on 9 February after 14 years away from the sport. So while I had an effective start point of 0 fitness, I had some old man reserves to draw from. Anyway, that two-month block with peak build weeks treated as mini-camps put my TSB at multiple times in the -35 to -50 range. I found that my training was still effective and the numbers were good in the -35 to -40 range, but lower than -45 was beyond my tolerance for fatigue. Were you able to identify any threshold for fatigue below which you felt like the session was bad?
So what’s my point? Backing down km’s or intensity (TSS), or taking a day or more off, or adding a rest week, are valid responses based off your fitness and fatigue. Maybe your legs were heavy, but the numbers were good? In those cases, embrace the suffering and ride through it and get the adaptations with a rest week to follow. If the legs were heavy and the numbers bad, take a day off and don’t force it: your body and spirit will both resent it!
During the first of my two training camps (planned 800 TSS weeks), I had a horrible ride. Mid-interval I pulled the plug, soft-pedaled home, and took two days off. That recovery let me come back and do a 3-day block of 516 TSS to close out the training camp with quality, and to slide into the planned rest week feeling content and strong. Then for my second mini-camp in May I was able to do two three-day blocks of 400+ TSS per block and 10,000+ feet of climbing per block with no problem. So the adaptations integrated. I guess I’m recommending #FTFP with daily shifts to allow you to hit your weekly goals without tanking an entire week and forcing a readjustment to the annual training plan…???
If we are “post-COVID” now, then the 20-minute FTP (raw, not normalized) numbers I have are 275 from March and 332 from May. I think that bump validates the approach… Or maybe just shows how badly I’m going to get dropped once racing resumes, haha…
