Pounding the Pavement

Spoiler

I'm not the best poet in the world, but I want to know what you guys think of this! It's a sonnet from my poetry anthology project.

Pounding the pavement, it is quite the treat
Her legs getting stronger, as one can tell
Rhythmic breathing keeps her rhythmic heartbeat
“Boys do not shower!” she hears her coach yell
Everyone there is chatting and chitting
She lags behind while they trot along
Having a ball on the road they are hitting
Being speed demons like nothing is wrong
Pounding the pavement… wait, what is this?
Pain takes over as she looks to the skies
This will not leave her with merely a kiss
More than a mile is her knees’ great demise
No longer rhythmic, her breathing is hard
Feeling as though she can’t go one more yard

Hey Emmylove.
So first of, congratulations on staying by the iambic pentameter. Your poem is structured like a Shakespearean Sonnet, so paragraphing it like this would make it a little more clear.

Pounding the pavement, it is quite the treat

Rhythmic breathing keeps her rhythmic heartbeat

Being speed demons like nothing is wrong

That way, you can really see the poem structure. (Which is abab cdcd efef gg by the way
Other issues-
In line three, the word rhythmic seems a little redundant. Replacing it in one instance may make the poem more elegant.

Everyone there is chatting and chitting

I don't know why, but I fell "Everyone there is chitting and chatting" would flow better. I understand you would also have to re-write the corresponding alternate line as a result, but it seems to flow better.
I may have phrased the poem differently, but then again, I don't write poetry, so I'm not the best judge.
That's all I have!

Unlike what the previous reviewer seems to believe, the poem is not in iambic pentameter. I mean... the second foot is inverted... and there are several lines that have more than five feet. Don't get me wrong, variations are okay, but here there is no design. Sorry I just didn't want you to have the illusion that you'd written a perfectly structured sonnet.

That said, writing in meter is desperately tricky and I don't feel as though I have any business attempting it.

Your rhyme scheme, however, is intact and I thought your rhymes were pretty decent: none of them seemed particularly forced which was nice.

I generally like poems about running I think, but I'd take a closer look at your word choice in general, the previous reviewer had some good ideas about that.

best,
