TR plans are HARD. Not sure I would even recommend them to beginners! I see two solutions:
- repeat base (up to several times), and/or
- use an alternative FTP test (the Ramp Test will often overstate your threshold - this may not be a popular opinion in TR circles but it can be quite popular outside them ;)) and/or
- do an alternative version of the workouts you find the hardest (i.e. a -1 version, or a -3 version if the plan says to do -1). This will help you finish the easier version AND the next workout (because you’ll be fresher).
Edit: you should be training in front of a BIG spinning fan! 100 watts minimum. If you don’t have one, get one and forget about my other recommendations.
