A British athlete just set a world record in marathon that Usain Bolt and Eliud Kipchoge have never accomplished.

Nowadays, the thirst to achieve even more with the historic race grows and apparently, 30-year-old Nick Butter from Britain has risen the bar higher than anybody else.

Just as the world thought that Kipchoge was already an extraordinary human being by becoming the first athlete to run a marathon in under two hours, Butter has now set a world first of completing a marathon in every country.

In accordance with the rules set by the Guinness World Records, Butter had to complete the extremely tiring distance in all 196 sovereign states. And this literally means all 196 without any exceptions. it also meant running through no less than 15 war zones, Give Me Sport noted

Despite the insanely huge numbers, Butter was able to complete 26.2 miles in Syria, Yemen and Afghanistan as well as African nations such as South Sudan, Mali and the Central African Republic where crime can be rife. And that also includes micro-countries such as Monaco and Vatican City where Butter actively had to monitor his location to ensure he didn't accidentally leave their borders.

After 22 months of running on the road, last weekend marked the end of his remarkable journey, which came to a remarkable finish in Greece – the birth place of the marathon distance.

Surely, there must be something very meaningful that kept Butter fueled in his bizarre act. It was later revealed by Butter himself that he had been inspired to take on the challenge after a close friend, named Kevin Webber, was diagnosed with prostate cancer. Butter didn’t only aimed to make history but was also able to raise more than £65,000 of his £250,000 target for Prostate Cancer UK.

As expected, Webber returned the favor and was present with Butter upon the completion of the 196th marathon at the Panathenaic Stadium.

When asked about his thoughts on the one-of-a-kind journey, Butter said he was "overwhelmed" to have finished such a fulfilling act.

According to him, he was "very tired" after completing the challenge, which took 674 days and involved visiting an average of just over two countries a week, BBC News reported.

"In one sense it was just another finishing line, but in a bigger sense I've been visualising it, and finishing in that stadium in Athens was so special," Butter said.

Currently, Butter has no plans of slowing down as he is now planning to continue running "one or two marathons a week" because he simply "loves to run.”
