Karl Meltzer Sets New Appalachian Trail Speed Record

Today we speak to ultrarunner Karl Meltzer about his new speed record on the Appalachian Trail.

On September 18, just over a year after Scott Jurek broke the previous record set in 2011, ultrarunner Karl Meltzer has bested that record by more than 10 hours. The 48-year-old Meltzer started his supported run on August 3 from Mt. Katahdin, Maine and completed the 2,190 mile (3,524km) Appalachian Trail in 45 days, 22 hours and 38 minutes.

The record breaking accomplishment comes after two previous record attempts in 2008 and 2014.

The 2,190 mile Appalachian Trail stretches from Mt. Katahdin, Maine, to Springer Mountain, Georgia, and runs through 14 states. Just to give a little perspective, the average hiker takes between five to seven months to complete the journey. 

We caught up with the ultrarunner as he continues to enjoy some much deserved downtime to discuss the highlights from his journey, trail diet and what’s next.

After 2 previous attempts, how does it feel to have finally set a new world record?
I don’t look at it as a “world record”. It is simply the fastest time on the AT. It does feel good to finally achieve the goal after trying two other times. Success is always gratifying, but with as much effort as it takes to do this, the recon and preparatory work was the real key to success. I’ve put a lot of time and effort into doing this, and finally I can say I don’t have to go back.   
 
What did your caloric intake consist of?
I consumed roughly 8,000-10,000 calories per day.  Spree candy, a good beer when finishing, and many sweet treats, along with an ice cold Red Bull at each stop. Ice cream was always a favorite too (when available) and lots of BACON!
 
What was your favorite section of the trail?
I like the Max Patch and Roan Mountain areas the best. These are above tree line sections in North Carolina. Also, New Hampshire has the White Mountains and Mt. Washington, which are all above tree line.
 
Aside from the obvious (completing the trail), what was your favorite highlight?
Being able to walk, jog, and hike in the “woods” is the real attraction to the trail. The AT is a true green tunnel, which is the real beauty of it all
 
What was the toughest section of the trail?
Mahoosuc Notch in Maine, or the Wolf Rocks section in Pennsylvania. Both are very different, but crazy hard, rocky and technical.
 
What was the longest section completed between crew checkpoints?
24 miles. A section near Sugarloaf Mountain in Maine.  It takes about 8 hours to hike quickly thru it.  It is very technical and hilly.
 
Did you do anything different this time in preparation for this attempt? 
I set up a stellar crew. This time, the crew worked perfectly. In the past, it was a scattered selection of random friends. This time, we did recon with the crew 3 times. Therefore, they knew everything on where to go, what to eat, etc.  It was super helpful.
 
For those that did not follow along daily, what did a typical day look like on the trail?
I would typically wake up at 420am, and hope to get on the trail at 5am.  We would have meeting locations mapped out the day before, and I would meet the crew at these locations where they would feed me, give me some supplies for use on the trail, then tell me how far to the next one.  At the end of the day, I would wash my feet, check for any issues with them. After washing my feet, I would ice my shins and eat dinner at the same time. Once I was done eating, I’d go right to sleep. Usually, it was about a half an hour after arriving. It was very efficient to give me the maximum amount of sleep.
 
Scott Jurek broke the previous record last year and lost a significant amount of weight in his attempt. He maintained a vegan lifestyle, how did you fare during your attempt?
I lost only three pounds, and have gained it back and then some already. I would never be able to do it vegan style. Bring on the bacon.

You hold many records for ultrarunning, what’s next for you?
I don’t have any real plans right now as I’m decompressing. Perhaps I will go for the 50 and over record at Western States 100, assuming I can get in.  And, to play many holes of golf.

Should you go hiking in sandals? It depends
Hiking in sandals: When to do it and how to find the best fit
Man hiking in sandals

Have you ever trudged through a trail, feet sweaty from unbreathable shoes? I certainly have. Believe it or not, sandals aren't just for the beach. They're actually a legit hiking option if you have the right pair and use them in the right scenarios. Honestly, I'm more of a trail running shoe or hiking shoe kind of gal, but there are specific scenarios when I might be tempted to trade them for a pair of sandals. And there are times when wearing sandals while hiking makes sense and times when they don't. Here's everything you need to know about hiking in sandals and how to find the best pair for your hiking needs.
Here's when hiking in sandals makes sense
Warm and dry conditions

When I lived in Arizona, hiking with my hiking boots or even my precious trail running shoes was a bit uncomfortable. For one, warm and dry conditions left my feet feeling confined and, ultimately, gross. One of the best parts of the day was heading home and washing my feet. That's when I was first introduced to the idea of hiking in sandals. Sandals will keep your feet ventilated, letting sweat evaporate fast. You may even find that you get fewer blisters throughout the season. Just make sure that you apply sunscreen so you don't get an unintentional tattoo of your sandal straps.
Wet conditions
While there's nothing wrong with wearing good water-repellant shoes while hiking in wet conditions, they can get soggy and take forever to dry if you end up accidentally stepping in too deep a puddle. Sandals tend to dry much faster than hiking boots or sneakers, so bring them on trails where you can expect stream crossings or coastal paths.
Low-impact trails
If you're planning on going on a low-impact hiking trail, particularly a paved one, you won't need heavy-duty hiking shoes. Sandals will be lighter on your feet, and the trail is easier, so there's less of a need for support or protection.

Tired of packed campgrounds? Farm camping might be your new favorite getaway
The camping alternative that's gaining popularity

Camping's popularity continues to grow, and outdoor enthusiasts are seeking less crowded solutions, from off-grid dispersed camping to luxury glamping. As a full-time traveler, I can attest that farm camping strikes the perfect balance between the two. I've camped in a lavender farm nestled in the California hills, an apple orchard in the heart of New England, and in an Airstream in Washington state's lush rainforest. These alternatives offer the natural respite of a campsite with the authentic charm of farm life.
Are you wondering how to find the perfect farm camping stay and what to expect once you get there? Here's everything you need to know to find and book the perfect farm-side experience.

This is the best ski resort in North America, according to real skiers
OnTheSnow award-winning ski resort you won't want to miss next year
Big Sky Ski Resort, winner of OnTheSnow Best Overall Ski Resort 2025 award

The 2024-25 ski season was such a blast. With above-average snowfall in many regions, there was plenty of fresh powder for everyone. Personally, I had the chance to visit two great resorts, including Terry Peak in South Dakota, and Ski Santa Fe in New Mexico, but they didn't win OnTheSnow's Best Overall Ski Resort in North America award. That honor went to Big Sky in Montana, which is definitely going on my bucket list.

As a visitor's choice award, this prize was primarily earned through user satisfaction, through ratings and reviews.
