Both times I attended ICPC world finals our team had only practiced once a week for 3-6 hours, but we were much worse than many teams that did not qualify from more competitive regions. The people who are the best at these things really do spend a lot of time practicing, though. The kid who beat Neal Wu at IOI practices 3-4 hours a day.
