Big time recovery from a nasty dose of flu after christmas and managed to sustain a CTL of about 80. My progress is a bit hampered by a lack of hilly outdoor riding for a variety of reasons, but largely work or weather. Happy with CTL but IF is dropping off as frequency is increasing in workouts. Not at all sure this is a good approach at all. You'll notice the 4 on 1 off went to 3 on 1 off. I like to get plenty of rest! Empty legs make for a junk workout anyway. To be fair, mostly it was enforced by life rather than me slacking :-)
