The Heat is On
You have set a valid lap time in One-Shot Qualifying.

When you play a season challenge, once you have selected your rival you will be taken to the qualification for the Grand Prix, and this will be "One Shot Qualifying".

You basically have one chance at setting a lap time and you must not cut corners, you must stay on the track.

You do not need pole position for this achievement just to finish the lap. You can use flashback if you make a mistake.
