Complete a lap at Motorboat Mayhem guide.
One of the week 4 challenges on season 13 is to complete a lap at Motorboat Mayhem, which is located right above Misty Meadows.
To complete this challenge you need a motorboat, there are a total of 4 motorboats on that location. Then you need to go here and a countdown from 15 will start.
When the timer hits zero checkpoints will appear, just follow them and get your xp.
To complete this challenge you need to do only one lap. This isn’t a time trial so you don’t need to rush it.
