DART 100K Challenge / Somewhat Legendary 50K

Have you ever gotten into a groove at a nice steady pace and felt like "I could run forever at this pace"? Now's your chance to test that theory out.
In the DART 100k Challenge, all you have to do is run a nice, easy 10k, once every hour, for 10 hours in a row. Easy! There are people who can run 10k in less than 30 minutes, and you get a whole hour to do it. That's a comfortable 9:39 pace. No problem, right?
The only hitch is that each 10k starts on the hour and ends on the next hour. If you don't finish in the allotted time, then you're out. The winner is the first person to complete the 10th loop (as long as they finish it in less than an hour!).
This challenge is intended to be a free, "fatass" event, but to ensure that only serious participants enter, you have two choices:
1: Sign up and pay the $100 entry fee (which will go towards food and race support)
2: Get a coupon code from race director Dave Munger and sign up for free! How do you get the code? Just join Dave for a run. All his runs are posted on the DART Facebook page. Or send Dave an email and explain why you deserve to get a code without going for a run with him.
Do you think think a 1-hour 10k doesn't sound like a lot of fun? For you, even more fun can be had by running 50k in 10k chunks, with a much more generous time limit of an hour and 15 minutes! That means you get a full 6:15 to complete 50k on the same course, provided you finish each loop in time. That's a super fun average pace of 12:04 / mile!
