Former rugby player-turned-adventurer Richard Parks has made it into the history books after completing the final leg of his 737 Challenge.
The 33-year-old used his climbing gear to become the first person ever to reach the highest summit on each of the world's continents and all three poles in the same year.
Parks achieved his goal after climbing Mount Elbrus in Russia, with the challenge dedicated to raising money for Marie Curie Cancer Care.
Speaking from the top of the mountain, he said the achievement had not really sunk in.
"It's really hard to put into words, just numb is the best way to describe it really. I'm sure when I'm back home and I've got the team around me we can reflect and I guess it will sink in then," WalesOnline.co.uk reports him as saying.
Parks will celebrate at a special welcome home gala dinner taking place on September 15th in the Marble Hall of Cardiff's City Hall.
