And first thing first is to do a proper ftp test, ramp or 20 minute. All other metrics are based on that… each interval, training zones, tss, etc. 71 tss for a 1 hr workout is not too hard. In fact hard days I feel should be more than 85 for 1 hour and easy days below that say less than 65. Just my preference.
TSS per week is highly dependant upon where you are at in your training and training history. Someone who has ridden for 10 years straight in a structured program will handle large tss loads better than a new off the couch cyclist. This builds year over year, don’t thin in terms of weeks or even months… think in terms of years of fitness building. For some 250-300 is enough to proved sufficient stress for fitness gains. For well trained athletes perhaps this needs to be 500. For pro athletes this can be more than 800 with some weeks up in the 1000-1200 range.
Normal weeks I would say to have 2-3 hard days. Hard days are threshold, VO2 max, anerobic, sprint intervals (Zones 4+). Then have 2-3 easy days in Zone 2, endurance zone, all aerobic work. Be consistent, hard days are after an easy day or rest day. Ride 5 or 6 tines a week so 1 day off minimum. Remember that working out makes you tired and adds fatigue, recovering from that fatigue is what actually makes you fit.
