Hour of power
This is a photo I took of the spin bike screen at the end of my workout. I was roughly following Adam Topham’s ‘Hour of power’ session, which is just one hour at the maximum level you can sustain. The problem I have is that the machine does not measure power. So I am approximating using heart rate. I estimate my lactate threshold to be in the low 150s (bpm). I did a 10 minute easy warm up then cycled up to 150 bpm and kept my heart rate at or just above it for 50 minutes. I did let it creep up towards 160 in the last few minutes. Average was 144 because the warm up is included. I will reset it next time.
