With 6,500 feet of vertical gain and loss over 31 miles through the rugged and technical terrain of the Red River Gorge in Kentucky, it is understandable why race director Michael Whisman of Next Opportunity Events (NOE) cautions against making the Rough Trail 50K your first ultra.

I’m in NorCal, few thousand miles away from home, running on a smooth dusty trail surrounded by giant trees. Once in a while, the green opens up and the sight of Lake Tahoe fills my eyes.

Well-stocked and friendly aid stations, serene trails and a low price point make Stone Mill 50 a great event to race, run your first 50-miler, or simply take a scenic tour of the best trails and volunteers that Montgomery County, Maryland has to offer.

For music fans of a certain age and disposition, it’s impossible to run past the legendary Folsom State Prison and not hear the distinctive voice of the “Man in Black,” whose performances inside of this place are legendary.

Located an hour outside of Pittsburgh, the Baker Trail UltraChallenge is a 50-mile foot race spanning single-track trails, dirt roads, pavement, footbridges, farms and forests.

Runners love Pinhoti. It seemed like everybody I talked to at packet pickup was either returning to run this race in Alabama because they couldn’t get enough of it or they were out to avenge a DNF. Pinhoti is like a flame in the night – drawing in moths, but also, ready to burn them into oblivion.

The Aussie spirit looms large at the Blackall 100 and for an outsider, it was all very captivating and magical. Would I ever return? Heck yes! Would I do anything differently? Yeah, I’d bring a bigger backpack. A person could live like a King off that checkpoint food.

Many people know about the HURT 100 – the Peacock 55 is put on by the HURT 100 family (Ohana). I was not ready for 100 miles, but thought 55 was attainable. Little did I know that while some people are able to complete the HURT 100, some have not been able to finish the Peacock 55.

Forested rock scrambles, 7,000 feet of elevation gain, and guided bushwhacks aren’t what you might expect for a 50k in Central Wisconsin, but that’s exactly what runners were challenged with in the inaugural IRONBULL Ultra Trail event, which has a unique mix of trail and urban running, finishing in the heart of downtown Wausau.

Runners experience a wonderland of rugged forest, waterfalls, natural arches, streams and river while tackling this demanding 100-mile tour of the Big South Fork National River and Recreation Area that begins in southern Kentucky and drops into Tennessee.

IMTUF stands for Idaho Mountain Trail Ultra Festival. The “TUF” is synonymous for the race’s difficulty and challenging mountainous terrain, the runners who tackle the race, and more accurately, the volunteers, like Vicki Trees, who unselfishly dedicate their time and energy, regardless of conditions or circumstances, to help others achieve their goals.

For the 10th anniversary of Tor des Géants, the Italian race organization created an even longer event, the inaugural Tor des Glaciers. By the numbers, it was 450k completed in a single push with approximately 105,000 feet of climbing—around 120k longer with 30,000 more feet of climb and descent than the traditional Tor des Géants.

Held in the middle of the night, this neon-drenched, 28-mile ultra took runners from the Bronx to Coney Island – through two subway stations – recreating the escape route featured in the iconic 1979 cult film, Walter Hill’s “The Warriors.”

The diverse terrain and trails at Hungerford – weaving through the Huron-Manistee National Forest and West Michigan countryside – continue to provide a beautiful backdrop for runners who come to achieve their goals.

The Marji Gesick is better known as a mountain bike race, but soon will be well known in the ultrarunning world as it offers both 100-mile and 50-mile runs.

Burning Man is about creating a community that’s about sharing. It’s about an experiment in being who you are, who you really want to be, who you can be, in an environment of complete freedom. It’s a place of participation and a place of no spectators. So of course, I had to create an ultramarathon.

The crux of the race, aside from the sustained altitude, is going over Hope Pass at 12,600 feet, twice — once at mile 43.5, and again at mile 56.5. Several finishers that I had spoken with imparted the wisdom that if I could make it over Hope Pass the second time, I’d finish.

It turns out this course has one of the steepest climbs in Ohio. Great. It also turns out that 95% of the 5,500 feet of elevation gain comes in the last 1/3 of each 25-mile loop. Fantastic. You see, I’m a flat and fast runner.

With a total elevation gain of 34,600 feet, the 100-mile course is tough but also very beautiful, traversing over three suspension bridges, a big dam and through many idyllic villages.
