i, am retired now but.
I have competed for 12 years as a pro in triathlon.
raced in the years 1992 until 2004.
Still competing, for fun.
But not any where near the level i was, or the level you are now competing at.
My pr's during a triathlon where:
1500m swim 18:01
40k bike 53:22
10k: 30:40 ( 28:58 for a course that was to short )
10k road: 29:26
Cycling: only road and cyclocross. mainly during winter, and some road race in the spring and fall, to keep a little intensity in the off-season.
I hope you have a great coach, that will help you achieve your full potential.
Hope that you make the national team!
Wish you all the best.
