I had a similar story. Been using structured training for a few years, but more so, within the last 2 and a bit years with TR, where I religiously, followed plan after plan. Even went off reservation and started to add extra’s - anything to build the FTP. It did the job, I managed to get 4w/kg from a fairly modest standpoint. But the work was bloody hard.
Although, I could manage the training stress, combined with psychosocial stress it insidiously dismantled me.
This really never gets talked about, we religiously do these workouts and yes, they’re fine and great for growing our Fitness, right at the begining. We look to others and hear people smashing out sessions and feeling great or hearing on podcasts, “of sucking it up”.
I went through a particularly dark place where my FTP decreased, I lost a lot of weight despite eating like an horse, I noticed biological symptoms of depression, anergia and worse of all anhedonia. But you know what I did, HTFU!! How bloody brilliant!!! And it just made it worse. I lost my love for cycling and it goes on…
I went through a right ol look into myself and realised that not we’re not all the same. And basing training on the best possible result 4 weeks ago is a nonsense!! The simple truth is, my FTP would be 300 one day, next 280. It just changes so much. But me, being me, I wouldn’t have it. I would cause myself increased mental distress if I couldn’t complete workouts. Or do, easier workouts and not heed the warning signs.
One of biggest signs for me, was my heart rate change. It was merely a marker, a flag that’s something is wrong. I feel this is not really addressed in TR and indeed, so many times over the podcasts it’s been said to ignore it. That maybe okay in a race, in training no!! At first I couldn’t get my HR up to an appropriate level and I thought, is this a problem, nah, just get on with it. Everyone else is. Then I noticed,. HR was disproportionately high per zones I were training. I just couldn’t win.
Enter Stephen Seller. This has turned my training upside down and literally for the past year, been the most welcome addition. Naturally, I have, messed about with the training, and got to a point where I think I have it right based around the scientific evidence and assimilated to me. Being a bloke of almost 47 (which I can’t deny is part of the issue) I’m literally training to my physiology and this has helped me to tune into myself rather than tailoring to a dubious percentage of a theoretical time. Nah!!
I love TR and still use it for my long focused indoor rides and of course hard day’s, like you say. But, listen to the body and mind, warning signs are there for a reason. Act upon and make a change.
