Help - I can't seem to improve my threshold power?!!
I am frustrated that although I train consistently I don't seem to be able to increase my functional threshold power which has been stuck around 220 Watts for the last year. I am 53 and train 6 days a week putting in about 120-150 miles a week including 2x 1hr interval sessions, 2x strength training in the gym and 2x longer rides at the weekend of up to 3 hours. But whatever I do my FTP seems to stick at 210-220W. Any advice on what to do to put out more watts? Am I training too much??
