I agree and only 10 finishers ever. You would think 100 miles in 60 hours would be easily doable for most good athletes. I don't know if you looked at the website but i believe nav skills and the ability to power hike for lots of hours are the key. Yes there are some runnable sections but i think the ability to do these at a decent clip but nothing out of the ordinary will get you thru. If you look at the guys who have finished it {not that i expect to} they all have long distance trail records which require the ability to power hike like you have never known. The elevation is lots and lots of 1000 to 1500 ft in 0.5 to 1.4 mile steep climbs again the hike comes in. The way to enter is secret so i can only hope i have the right details from a former runner and hope we are 2 of the 5 international admitted in December in a grand total of 35 runners.
