Is this really harder than Mount Baker Marathon? That one involves 108 miles of trail from sea to summit of 10,700 foot snow clad volcano.

This race adds a long ~100 mile run on the top of it. http://www.trailrunnermag.com/people/adventure/1495-revival-of-the-toughest-race-youve-never-heard-of http://www.trailrunnermag.com/people/adventure/1495-revival-...
