To complete any of the Stormy Run challenges, you'll need to land at Polar Peak, a volcano and on top of a hill with a circle of trees. You will therefore have to go to three points of interest on the map, and land there. You will therefore have to gain height to land there, or do it in three parts.

For this challenge, you will need to travel to Pressure Plant, to land on the volcano, at Polar Peak, and at the top of the hill south of Pleasant Park. You will therefore have to complete this challenge in three parts, or else launch yourself into a rat race to rise and descend in a glider on each of the places.
As a reminder, it's easier to complete this challenge in Team Rumble, then with respawning, you won't have to worry about dying.
