I came today across the website of this 100 miler run on the Cascade mountains; maybe for others here (read: fools) this run is old news.
And if this race is not yet part of ultra folklore, I'm sure it's fast on its way there.
100 ("+"...) miles, No flagging, no t-shirt, no pacers, no aid stations, "you receive nothing from anyone", no stashing, and to top it all off properly - "if someone figures out what they think is a cool way to use the above rules to their advantage over their fellow runners, I reserve the right to disqualify them."
