Wow! That's a great time and it's good to see another female world champ from GB, the first since Carolyn Hunter-Rowe (twice) I think. While 7:30 is a barrier for women, the womens' world best is a rapid 6h33m set by a Japanese lady! Often the mans' World and European title is won in a slower time than that! I have started several 100k events but completed only 3! It's bl00dy hard mentally! 6h54 best, 8h04 worst. That's respectable but the mens world best is 6h10 (on a 400m track!) set by Don Ritchie at Crystal Palace in 1978. Don still runs Ultra events today.
Wow! Very Impressive!!! the Italian looked very close in the picture so Well Done that Girl! on the subject of Ultra Runs has anyone attempted the 'West Highland Way' Ultra Run? it is Approx: 150km and has to be completed in under 36 hours...
Some probably do but many of the Marathon de Sables runners are 'different' to most human beings! A few years ago I was approached and asked if I would train a guy to do the MdS, he went from perfect vision to just 20% vision and wanted to be the first blind man to run the event. He would need a guide runner, we found one (not me FFS). However, I spoke with his wife and we agreed that despite his best efforts he could die from such an event due to him not being willing to cover the training (I'd take him to a gym treadmill 3 times a week). Since then a complete blind person has completed the MdS successfully.
A 7h30 100k runner would cover the marathon possibly in the 2h40 - 2h50 region. I've met many elite male marathon runners who suffer and fail at the 100km event. Then I've met very sucessful Ultra runners who are mediocre at the marathon. I think it was Sunada (Japan) with a Marathon best of 2:12 who holds the 100km road best of 6h13. However, in 1999 he did not respect the 100km distance at the World Champs and passed the Marathon point of the 100km in a blistering 2:26!!! His wheels fell off but he managed to hang on for second! He returned to the Marathon and has since run 2:10.
