For some, running a marathon is a lifetime accomplishment in itself. For Pete Kostelnick, he's done one by noon every day. The 'ultra runner' is already in the record books for his determination, but now he's on to a new challenge.

Kostelnick is in the midst of a massive 'Ke2Key' run and is trying to be the first to accomplish the feat. On August 1, he started his trek from Kenai, Alaska and will eventually end up in Key West, Florida. The superhuman found himself in Estevan last night on Day 52 of his journey.

"It'll end up being about 8,500 kilometres total, or 5,300 miles. I hope to do it in about 100 days. I'm right on track right now. This is day 51, so I've just started the second half," Kostelnick said.  

This isn't the first insanely long journey Kostelnick's legs have taken on.  Back in 2016, he ran from San Francisco to New York City in 42 days, 6 hours and 30 minutes. That journey was a mere 3,067 miles, or roughly 73 miles – 117 kilometres – per day. A standard marathon is just over 26 miles or 42 kilometres. He was the fastest to ever accomplish such a run. 

For many people who hate running, they could never understand why Kostelnick would ever want to take on such a challenge. 

"I like getting out there, outside the box and breathing the fresh air. I love it," he said. "A lot of people wonder, 'Why would you want to run that much every day?' It's something I get to do, every day is great, every day is a little different. It's been quite the journey and I hope it will be the rest of the way."

On his website, Kostelnick lists a few reasons as to why he started. He wants to promote a healthy, active lifestyle and wants to show people how to dream big. He's always loved running and wants people to understand how having faith in yourself can lead you to accomplish big things. 

Although Kostelnick is an amazing athlete, even he admits he has to take it easy sometimes.

"It's not just running as hard as you can. I always tell people, 'if you can't run then jog and if you can't jog then walk'" he said. "I'm not running seven-minute miles all day. I walk a little bit here and there."
