How in the heck do you beat Mecha-Marathon in Mini-Game Coaster in Mario Party 2


I can barely get 20 yards. How do I beat it successfully? I button mash the heck out of the A+B buttons. I do this on the GmaeStop refurbished GameCube controller. Should I do it on the Classic Controller original (don't have Pro version)? Also does this glitch work for you guys or does it only work on the N64 version for this mini-game?:

My back is ACHING for trying to beat this! I need to buy battle mini-games then aqzuire Rainbow Run!

I am playing this game on the VC on my Wii just to let you know. It came out on Monday.
