In yet another of the events in his well-publicised (and extremely well-supported) runs in "Kilian's Quest", Kilian Jornet ran to the summit and back in 5h19m45s on June 10, 2011. Kilian started in Dion and finished in Litochoro. He said, "I used the race route (Olympus marathon: https://www.olympus-marathon.com/en/race-course/sketch ) so starting at Dion and finishing at Litochoro (in a big park in the middle of the city), and where the race goes under the summit I was going up and climbing the 2 main summits, then down other valley."
Here's a press release copied from www.suunto.com:
Greece 10th June 2011
This morning Catalan athlete Kilian Jornet, broke a new record reaching the summit and descending from mythical Mount Olympus in Greece, with a time of 5:19:45 h, in this first challenge in Kilian’s Quest season 2011.
The route was 45 kilometers long, with over 2.800 meters upward slope in the first 22,6 km, a total upward slope of 3,508 meters and a total downward slop of 3,228 meters.
“I felt good on the way up, although my legs were slightly tired, from these last days training, I guess. The technical side of things went very well and I really enjoyed the descent, which was long and technical.”
The anecdote of the day arrived when Kilian took the wrong route by mistake and reached the Summit of Mount Stephanie “I took the wrong route and climbed to the summit of Mount Stephanie, where I realized a mountain ridge was keeping me away from Mount Olympus. I tried to go round it but was unsuccessful, so I had climb down the path and take the right way to Mount Olympus. It took me about 20 minutes, but, as I say: “More kilometers means more fun.” “It gave me the chance to enjoy new views”.
