AverageGuy said:I just started training with power a few weeks ago after completing my first FTP test. My question is...
Is there A % of my present FTP I should try to increase by?
I'd hate to start the next test thinking "well gosh...I'll just try and go a little harder."
A couple of comments. First, your FTP doesn't increase because you test it frequently. It increases because you spend a lot of minutes at L4 intensity (91%FTP+). You can do this on long rides or short rides in segments of at least 10 minutes. If you did your FTP test with a 20min test, then I assume you had an average power of about 212W (*0.95 = ~202W). If you are going to do 20min efforts, you will increase your FTP if you ride them at 90%+ of your max 20min power. IOW, you can ride them at about 190W or greater.
As to when to increase your FTP estimate, you can go by how your 20min efforts feel. When they feel too easy at 190W, then increase your power by 5-10W. In fact, I sometimes ride for months without re-testing my FTP, yet I know I am increasing my FTP because my efforts at all durations get easier and I just increase my power to what feels about like 90% of my max sustainable power for a given duration.
Finally, as to how quickly you can increase your FTP and what your potential is, nobody can tell you that because it's a function of your genetics and your self-discipline. I can give you one data point. A few years back a guy in his 50s who had never ridden before joined my cycling club. When we first rode together, he didn't even know what gear he should be in. I took him out to a favorite climb and we figured out what his sustainable power was at that point in time. It was about 200W, about the same as you. I suggested that he do the climb at least 3x per week, then group rides on the weekends. I told him to simply increase his power by about 5W whenever it felt too easy at whatever his target power was at that point in time. That was in September. He was very disciplined and rode the hill 3-4 times per week, plus weekend group rides. By Christmas, he was riding the hill at 300W. Not that you will progress as fast as he did, but that it is possible and without a huge number of hours.
