Every Time I play this game and try to speedrun it I overeat how do speedrunners not overheat just want to know so I can actually get run sof the game

Well, there's a couple ways to avoid overheating. Ride over the cooldown arrows and use A instead of B (until you reach a cooldown arrow). The more advanced way is to release B anytime you're in the air. If you watch closely, your TEMP meter will drain a small amount if you release B while in the air. Over the course of a race this adds up to alot of temperature drain if you do it everytime you're in the air.

OK thanks will try it when I get the chance
