Karting Microgame, I would like to put a jump into my track.

I am very new to unity so any help is greatly appreciated. I've made my first tracks layout, it has 2 jumps. The first one, if you clear the jump your lap time shortens but if you fail the jump you get taken on a longer path. The system works for the most part but when you hit the jump if you try to roll through it you get stuck on the edge of the prefab but if you jump just before you hit that "barrier" you clear it perfectly. How do I make it so you can use your speed to clear the jump, as if its an actual ramp per say?
