Hey everyone I could use some advice. From a background perspective I got back into cycling this year after several years off. I am certainly not new to interval training so I knew what to expect coming into this year. Starting in March I started a low volume base plan, and completed Base II, Build I, Build II. I started this year with an FTP of 143 and testing end of September at 233. I noticed at the start of cross season that I was not able to keep up and after some review felt like my biggest weakness was muscular endurance. So instead of moving into my specialty phase I started back in base II. During my ramp test for Base II I tested at 222 watts. Thinking it was just a fluke I left my ftp where it was and started my base plan. Unfortunately I cannot complete these workouts and this morning took the ramp test again and tested at 198 watts.
Looking for perspective here, what do I do? My current plan is to accept that my ftp has gone down for some reason and stick to the base plan at the lower wattage and see if I can start to build my power again. While this super sucks, the biggest bummer is that this has happened right in the middle of cross season and I just seem to be getting slower and slower.
Any advice is appreciated. Thank you!
