I am currently in the final week of short power build low volume. I ride my bike for about 10 to 12 hours per week as I add more endurance rides. Although I use my trainer year-round, I also do outside workouts which add 30-40 TSS on top of the original workout as I need to ride for some time (on steep hills!) to get to quiet roads where I can do my intervals. As a Zwift user, I arbitrarily choose group rides to join on the days which I don’t have a trainerroad workout, and sometimes these zwift rides are long. The progression for the second half of short power build has been:
Week 1: 738TSS (I did 2 one hour runs and I am pretty sure the TSS is under/over estimated).
Week 2: 553TSS(I did 3 runs per week. 2 one hour runs and one 30 minute run. All were done at ~150bpm heart rate which is the tempo(power) HR for cycling)
Week 3: Pretty sure it will be more than 553 TSS.
So the question is, should I strictly follow the progression? I chose a low volume plan so I can mix it up with endurance rides and I also find it easier to stick to a low volume plan.
