There's no denying marathons, or any running race for that matter, are hard. You have to pound the pavement for hours, sweating and panting until it feels like your legs are going to give up on you.
So imagine the strength it took one athlete to not only carry herself across the finish line, but a random dog she met along the way.
While many wouldn't let a stray animal get in the way of their race, Khemjira slowed down to see if she could find its owner.
The athlete quickly realised that no one was standing along the side of the road cheering people on and there were no houses close by, so the bangkaew - or Thai wolf dog - must have either been lost or on its own.
What she did next was out of this world.

The 43-year-old picked up the small dog and decided to carry it all the way to the finish line, which was 19 miles away.
The shop owner has now adopted the puppy, believed to be just a couple of months old, and named him 'Chombueng' after the name of the marathon.
Khemjira said: ''It seemed to me that this little guy was lost. There were no houses, no other dogs, or no people around. So, I picked up the puppy, if only to take him out of the unsafe environment.''
That's not even the best dog x marathon story that's ever happened (although I would probably watch a Netflix movie about that).
A two-and-a-half-year-old Bloodhound managed to place 7th in a marathon in Canada after being let out to use the bathroom. He crawled under the garden fence, ran towards the start-line and, well, the rest is history.
Ludivine even stopped at the two-mile point to sniff a dead rabbit.
It is also believed that the dog went off track on a number of occasions, including the moment he played with a herd of cows. THIS ACTUALLY HAPPENED. Imagine the runners who had trained for months to tackle this race and nearly all of them get beaten by a bloody dog.
His pitstops didn't deter him from securing a respectable position, though, crossing the line in just over an hour-and-a-half.
This might just be my favourite story of all-time, ever. Congratulations to Ludivine the Bloodhound. Enjoy your success.
