Ester laughed, letting him take the lead.

If there was anything that she could learn in all of these years living with the old rabbit was how to be a fast runner.
Moreover, she was a hare: she was endowed with larger feet and longer and stronger hind legs than her father. Therefore, she was able to run as fast as the wind.
Maybe even faster.

«If ya can’t race da ol’ man, how d’ya think ya can race me?» She said, preparing to run.
She dashed through the wind, shortening the distance between her and Jack in a matter of seconds:

«Told ya, Frostbite! See ya around!» She laughed, teasing the Winter spirit before speeding up.

Jack rolled his eyes as he watched Ester run past him. He knew she was a faster runner - she was a hare, after all. But of course, he would never give up that easily.

He tried to pick up speed and rode through the wind, until he was able to catch up with her, but not quite getting ahead. “Not bad, Ester,” he got out from behind her. “But you can do better than that." 

A thick tree branch stood in the way a few feet in front of them, but because Jack was light as a snowflake, he was able to dodge it with ease, getting faster as he began to take the lead. He let out a laugh as he went farther and farther away from Ester, but never left his guard off.
