I’m not in a position to purchase a power meter or smart trainer so I have been getting by using an old Kinetic trainer with their virtual power hardware (InRide) based on a good review from DCRainmaker.
I’ve logged many hours of indoor training with this set up and it’s resulted in some good power increases.
However, lately I have noticed that my workouts are feeling “off”. I peaked at a threshold of 320w in 2018 and have dropped down to 302w based on a ramp test taken last week. I dialed back the riding quite a bit in December after CX season, and have only averaged 150ish TSS since
In the last couple of weeks I have noticed 2 things.
The trainer spindown number (time?) has gone from averaging 1.6s to 1.9s. (what does this indicate?)
Coinciding with this, my workouts feel tougher. PRE/HR for sweet spot workouts feels like threshold.
Could this be a mis-calibration of my trainer/InRide unit?
Are my legs fried after being 6-weeks into a weight training plan, making everything seem harder?
Could this be due to me not being as fit as I was 6 weeks ago (during cross season)?
Help me understand how accuracy can be affected by wheel tension, cold vs hot spindowns, tire pressure, and any other factors I’m not thinking of. I want to find a consistent and repeatable set up for this trainer.
