A 50 That’s More Difficult Than Your Last 100

How do you build a 50 miler that hits harder than most 100 milers?

Easy.

Start with a stout mountain hundred miler. Anything with ~24k feet of climbing should do.

Find 50 miles of flat and discard it.

Add copious amounts of highly-technical, unforgiving, why-would-they-even-think-this-is-a-good-idea trails.

Make the average elevation nearly two miles above sea level.

Set it in the most stunning mountain scenery in the lower 48 states using a (patent-pending) broken-windshield race format.

Add amazing, die-hard volunteers, an incredible community of runners who are low-key badasses, questionable race organizers, all-you-can-drink Dr. Thunder, and all-you-can-eat generic sour cream pringles.

Oh yeah–and two orange traffic cones for a finish to keep your ego in check.

CALM DOWN IT’S JUST A RACE!!!
