Highlighting the emotions of the characters

Right now jogging was the word of the week and although the others were thrilled about it, Lacey couldn't see the hype quite yet. She had never been the fastest, her lungs had the bad habit of running out of breath after a few meters and the city wasn't making it any easier either: loud noises mashing with the sounds of her ear phones, crowded avenues, dirty parks, rude people and unwanted looks, and above all this reigned the heavy smell of oil and exhaust gas. So here she was, 15 miles away from civilization, trying to find a new passion. She had to admit it was beautiful, although she couldn't help but throw a look behind her once in a while.

"I mean no disrespect, but I ain't picking up the check

Taking selfies on your phone while you're breathing down my neck"

Lacey was only turning her head back to the road when out of the corner of her eyes she caught a figure dashing over the trail into the bushes on the other side.

She stopped dead in her tracks, throwing a scared look around and trying with trembling hands to stop the music on her phone.

"It's gettin' pretty fuckin' old, and I'm almost nearly done

I'm glad that you were happy—here's another number one"

It was secured with a special support to her left arm, near the shoulder, and now she was trying without success to get to the playlist and stop the damn things from screaming into her ears. For her eyes the phone was upside down and her fingers were shaking so violently that she just kept opening random apps, then trying to close them and look again.

She dared look up for a split second, only to see another figure (or maybe the same?) dash between the boulders. Her heart started beating absurdly fast and her breathing intensified as she felt panic engulf her, taking hold of her every limb and hair on her body.

Lacey was now furiously fumbling around the phone trying to pry it off for a closer look, but her fingers were blind, she just couldn't find the clasps! Another figure jumped across the trail right in front of her, this time close enough for her to make out 4 legs boosting it forward. She had no idea what it was but it was closing in. She felt her finger tips' skin crack open and her nails break from the scraping, but she just knew she couldn't stop.

"All in all, it's a good life

I got what I want

I can't complain"

"Clack!"

The clasp finally opened and her phone tumbled down, missing her bleeding fingers and crushing onto the rocky ground. Lacey had the urge to bend down and get it, but a divine like moment of inspiration gave her the thought she should have had from the start. She snatched the airpods from her ears and closed her hand shut around them.

Silence. Lacey took a deep breath and slowly turned her head around, scanning the surroundings for the first time since she stopped. She couldn't see any figure now, not on the trail, not in the bushes or between the boulders. The edge of the forest laying right below the trail was still and quiet, only the leaves moving with the wind. She took a step closer to the ridge and craned her neck to take a better look, trying to make something out in the shadows. And just then the darkness hit her. There was no dusk anymore, the sun was long gone, there was just the night left, and suddenly the previously beautiful place was downright creepy. If she felt uneasy before, now she was terrified.
