“Do you want to come with me?” Kelly asked her brother, “I’m going to meet some friends at the bike course. We’re going to practice for the race next week.”

“No, thanks,” Marcus replied. He was sporty. Most sports were a piece of cake to him. He knew he would win.

When the race day finally arrived, Marcus and Kelly rode their bikes to the Oak Park Trails with their parents.

“My stomach feels like I ate some butterflies,” Kelly told Marcus when they saw the crowd of kids.

“Don’t worry. You’ll do fine,” Marcus said.

The starter shouted “Go”. Marcus quickly rode to the front. A few minutes later there wasn’t anyone ahead of him! Marcus raced along the trail. Time passed, and he was surprised that the course was so long.

His tired legs felt like they weighed a hundred pounds. All at once, a flash of color caught his eye. There was a line of bike riders ahead him! “How could this be?” Marcus said to himself as he pushed forward. “I must have taken a wrong turn,” he thought Marcus tried hard, but he realized his speed wouldn’t be enough this time and bike course was just as important.

After the race, Marcus saw his sister at the finish line, and he rode over to her. “Wow, you must have done a good job in the race. What place did you get?” Marcus asked Kelly.

“I came in third place. Mom and Dad said I would even receive a medal(奖牌)!” Kelly answered excitedly.

“That’s great! I came in ninth place. But I’ll do better next year because I’ll be smart enough to practice the course with you,” Marcus replied with a smile.
