I got diagnosed with this about 18 months ago, finished my hormone and radio therapy treatment the end of July and are now currently just having my blood monitored for the next 6 months.
Started doing a little exercise on the turbo zone 1 and 2 a few weeks ago, so yesterday I decided to do an FTP test just to give me a marker going forward. As expected it was well down, by half! Anyway what I don't understand is that although my heart rate could reach zone 3 tempo and occasionally touch zone 4 my power output was no different to the same effort I had been getting at zone 1 and 2. Anyone been here with this before, advice would be gratefully appreciated.
