There are 3 types of challenges for the night mode on Whispering lake.
Night Rider:
Complete a nighttime run with any bike.
Beginner:
- 3:00 or Less
- Under 20 Crashes w/Grasshopper
The Grasshopper can't handle big drops, but there are very few on this trail so just keep to the paths you're best at. The requirements are very forgiving.
Free Ride:
Complete the map without checkpoints in the dark.
- Cross the finish line with the Geronimo.
You should know where you're going by now. Just be careful and don't worry about the timer.
