Top speed challenge rewards really require a full team of good racers. You can only set on fastest time. It's not like the endurance events where a single player can get rewards by running for a long time.

This event is also subtly different from normal as it looks like you will have to set your top speed without going off track. Normally, top speed challenges are all about running fast and crashing into walls.
