Someone helped me with an idea I didn't know how to expand

Jogging wasn't much fun alone; Kayla knew this better than anyone. The pounding of her sneakers on the asphalt resonated in her ears, though it did nothing to break the monotony of her thoughts. That was where her mother always came in. Together they would run, taking in the morning breeze and sharing the music of nature. Talking wasn't necessary; the sound of her mother breathing next to her was enough. It had been a year since Kayla lost her mother, and running, it seemed would never be the same again.

On the few days she actually did remember to bring her iPod along, it did little to help her ignore the loneliness.  Even still, running was not something she could give up.  It was the last connection she had to her mother.  Although painful, it was nice to have that time to reminisce on the time when she felt the strongest connection to her mommy.
