Humbled by the wind - 1/2 Ironman New Orleans

I finished my first 1/2 ironman. The bike and run were billed as flat and fast. And the bike could have been except for the gale force winds. I finished in 5:30:21 and I am truly humbled. I know everyone always does this but I already see minutes for improvement. About 8 in the swim, 8 - 12 in the bike and 15 in the run. How do you do a sub 5 hour 1/2 ironman - first do a 5:15.
