Fortnite: Chapter 2 Season 3 - Complete a lap at Motorboat Mayhem
For this Week 4 challenge, you'll need to complete a lap around Motorboat Mayhem to earn your XP.
Motorboat Mayhem is a special motorboat race track that can be found near Misty Meadows. If you visit the area, you'll see a race track set up already in place with various ramps and obstacles.
You'll also need to find a motorboat, which shouldn't be too difficult given the volume of water covering the Fortnite map.
This challenge isn't too difficult to complete and there isn't a time limit, you just need to make sure you stay on track.

You can find the start of the track just to the north of Misty Meadows and there should be some motorboats nearby.
Once you've hopped into a motorboat, head to the start line to begin the challenge. You'll need to speed and jump through the blue rings around the track to complete the challenge, including going up a few ramps. Watch out for enemies and remember to sue the boat's weapons if you encounter them.
Once you're done, you'll get 35,000 XP for your troubles.
