After two weeks only riding on Saturdays outside, 197 and 242 TSS, I came back to the trainer and did a sweet spot session.
My RPE was normal to low.
My power was good.
Heart rate was at threshold level, ±90% HRmax
After toning down my power to match the max sweet spot HR of 85% I finished my workout.
I compared that workout to the same workout twee weeks back and three weeks back and found that my cadence was 5-6 RPM lower the weeks before
Old RPM - 92-93
Last RPM - 96-97
Can my HR be explained by the increase in cadence or did I lose some fitness???
