I did two mostly zone two rides this weekend. My CTL was around 52 two weeks ago and is perhaps 50 now. If I do nothing for the rest of the week, my TSB would rise to 14 bringing me close to the 15-30 range I read about for a big race day. My coach instead scheduled a lot of rides for me including a 46 TSS ride just the night before. Is that common? Im 34, work a challenging full time job, and am relatively new to cycling ( 2 years of doing it more regularly, FTP is probably around 220 +-). I was surprised at doing any more training this week so a 46 TSS workout the night before a very early really long event struck me as odd. I have no experience though so just wanted to hear from others how common this is.
