Now THIS is a real endurance athlete!

From multi-days. com: Yiannis Kouros gets more than 600 miles in a six day race!

Most of us dream of getting 100 miles in a single 24 hour period. A (relatively) few of us have actually done it; I am one of those. (I walked 100 percent of the time, but did not become an official centurion as there were no walking judges there; so I got "credit" for finishing the distance as a runner).

Then, we heard the flap about Pam Reed and Dean Karnazes and a 300 mile race. Pam Reed made the 300 miles in just under 80 hours. Both Reed and Karnazes are excellent ultrarunners, with wins at the Badwater 135 mile desert race. Of course, John Geesler previously covered that distance in 69 hours, (Across the Years, 2004-2005) but never mind.

But then, we get what Kouros did:

RACE RECORD By EVERARD HIMMELREICH
November 28, 2005

GREEK distance runner Yiannis Kouros scored a sensational victory in the Cliff Young Australian Six-Day Race on Saturday at Colac, smashing both the world six-day track record and six-day indoor record with a distance of 1036.85 kilometres.
Race commentator Phil Essam said he had doubts Kouros' feat could ever be repeated.
Kouros, 49, set the previous world six-day track record of 1023.2 kilometres in 1984 at Colac and said he never expected to beat it 21 years later.
Running on about three hours' sleep for the six days, Kouros was never challenged. Organisers hailed the 20th race the best ever, with a number of other veteran competitors setting world record distances for their age categories.
Kouros said he had done a lot of preparation for the event in Greece this year, running the double Sparthathlon and the Athens marathon in record time for his age group.
He came to Colac with the aim of setting a new world record.
He set himself distance targets each day and only struck injury problems early on Saturday morning when he strained his hamstrings doing stretches.
With the records in sight and with the help of urging from a contingent from Melbourne's Greek community, he surged through the pain barrier to set the new world standards.
A fierce wind storm on Friday night created a challenge for competitors, bringing down half of one of the large elm trees that line the course around Memorial Square.
The large limbs just missed Warrnambool runner Alby Clarke, who heard the tree cracking and increased his pace to get out of harm's way. Organisers directed the runners around the tree limbs while they cleared the timber.
The incident followed another on Thursday when a gas cylinder used by one of the runners' support crew caught fire, stopping the race for seven minutes.
Kouros' win gave him not only the $5000 first prize but also a $5000 bonus for passing 900 kilometres and another $2000 for breaking the world record.
Runner-up was Czech Vlastimil Dvoracek who clocked up 822.8 km, more than 200km behind Kouros. Third was Katsuhiro Tanaka of Japan on 814.4 km.
Frenchman Claude Hardel, considered one of Kouros' main challengers, had to pull out during the week with foot trouble.
Thirty-four runners headed off on the epic foot slog and more than half a dozen pulled out during the race.
Clarke, the first indigenous Australian to compete in the event, finished with a distance of 344.8 kilometres while Camperdown's Don MacKechnie did not finish.
