I did pretty well. I competed in 6 events, podium in 3. Took 2nd in forms, 1st in weapons (the form above) and 2nd in combat sparring.
As far as training time:
~5 hours forms (traditional and "XMA" which is more gymnastic-y) and gymnastics.
~3 hours weapons (traditional and "XMA")
~3 hours sparring (combined drills and match style)
I do a 3-4 hour straight sparring class (for our team competition sparring) once a month, and another 3-4 hour elite sparring training about quarterly, and then one 9 hour/day for 3 days sparring camp annually as well.
Beyond all that, I try to run 2-3 miles 3-4 days a week, and walk the same on the days I don't run, just to push cardio. I also do various stretching and light strength training things throughout the day on breaks to try and keep the joints/muscles happy-ish.
Injuries suck.
