Ive been using trainer road for a year now and I went from 190w to 300w in a year.
I averaged 3-4rides a week for the whole year.
Can I get to 400w FTP in another year or so if I continue to put in the work?
That's excellent progress and you should be very happy (assuming your numbers are accurate, that is). If you learn to pace yourself well and really work on your aerodynamics you can achieve very good results in triathlon on 300 watts at your weight, and you can certainly consider bike racing as well. Whether through lack of proper training or genetics a majority of triathletes will never reach your level. You likely can improve more and even modest improvements at this point will have significant impact on your results. By all means keep working at it and see where you can get but the likelihood of reaching 400 watts is very, very low.
