From watching that video my tip would be to use your items more logically. Don't throw all your bananas away as they can be used as a shield, such as when all those people bumped into you right after you threw them. (Plus, you ran into one of them the second lap.) Try to use mushroom boosts at strategic points to cut through grass instead of blasting them off one after the other as well. That should help some.
But better job at using some boost charges.
