You cheat

"Ready... go!" Allison announces, and before you can react, she's already 20 feet ahead and you start to run after her. At first, you're feeling good and confident, but as you look ahead, you see the distance between you and Allison get wider and wider. You thought you were going pretty fast, but Allison seems to be on a full sprint and if you don't do anything soon, you're going to lose sight of her, not to mention have no chance of catching her.

****, you activate your teleportation ring, and quickly teleport ahead so that you're only a few paces behind Allison. You get there at the same time as she just looks over her shoulder to see you right behind her, and she looks surprised and impressed. You smile and wave at her, and she turns back to focus on the road and trying to lose you.

You don't want to draw suspicion by winning too easily, so you let it go on for a while, really having to run to keep up but using your teleportation power periodically so that you don't lag too far behind. Allison looks back a few more times, each time thinking she has lost you, only to see you trying hard to catch up.

Finally, even with the help of your magic rings, you're huffing and puffing and struggling to keep up the appearance of running fast, so you teleport ahead once more until you're less than a foot behind Allison, and then you tap her on the shoulder. You hang onto her shoulder for a few more strides, before Allison eventually slows down then stops. She looks at you in amazement.

"Wow! I think know you had it in you! Amazing!" Allison says. While you're gasping for air heavily, she's breathing normally like she's on a walk. You hold up a finger, indicating you need a minute or 2 to recover, and Allison chuckles. She pulls you to the side of the road as a car zips pass.

"...Gotcha!" you finally say when you can.

Allison smiles and nods sportingly. "Yes, you did. Tomorrow I'm going to make it tougher."

"But today, we do my idea of exercise, right?"

Allison looks down at your shorts. "...Okay. Race you back to the estate?"

"Or we could do it here?" you say hopefully.

"Haha. No way! Not by the side of the road! Come on!" Allison says, already starting to run back.
