You can't train any more than you have. So what is the answer? Train different?
Get it next year.
(One swimmer had a guy he couldn't beat, so he trained harder. Next big meet he only lost by a fraction of a second. So he trained harder. Next meet his nemesis crushed him big. Both swimmers ended their competitive swimming but met up one day. The one said, I almost beat you once, so I trained harder then you crushed me.The winner replied, I knew you were gaining on me, and I knew I couldn't train any harder. The only thing left was to train differently.)
