Colin O’Brady is Attempting to Cross Antarctica Solo, Unaided, and Unsupported

Colin O’Brady is attempting an impossible first: be the first person ever to walk 1,000 miles across Antarctica alone with no help and no food caches. To complicate things, British Army Captain Louis Rudd is trying to do the same thing at the same time.

We talked with O’Brady just before he left Punta Arenas in Chile for the chilly expedition.

On November 3, 2018, O’Brady started dragging a 400-pound sled on top of the ice of Antarctica. He has enough food for 70 days. Either he makes it in under the deadline or uses a satellite phone to call for rescue — and hope it can arrive in time.

The Risk

Solo, Unsupported, and Unaided

The record requires O’Brady to be unaided so he can’t use any machine or animal for help. People have used kites in the past to pull them up to 200 miles per day. Talking to O’Brady, he made sure to point out that’s a vastly different trip than the 10-20 miles he hopes to ski per day. Unsupported means he won’t have food drops or caches waiting for him along the way. He has to carry every ounce of food he’s going to eat for 70 days. And solo, of course, means he’ll be alone. Just the ice, a sled, and his own thoughts for two months.

Everyone Else Has Given Up (or Died Trying)

Everyone who has tried a solo, unaided, and unsupported trek in the past has been unsuccessful. Ben Saunders attempted the record in 2017 but ran out of food and had to call for rescue. Henry Worsley tried in 2016 and nearly made it. Weak from too little food near the end and a bad infection, he called for rescue but died two days later in hospital.

The Gear

What to Eat

One of the biggest problems with walking across Antarctica is getting enough calories. He’ll be walking 10 to 12 hours per day dragging a sled that weighs nearly 400 pounds. Not to mention the longest leg of the trip, from the start to the south pole, is all uphill. The South Pole itself sits on 9000 feet of ice.

O’Brady will eat nearly 5000 calories per day of custom-made ‘Colin Bars’. For a year before the expedition, he worked with doctors at Standard Process, a company specialized in whole food and nutritional supplements, to create a source of food perfectly formulated for Colin’s physiology. Each bar is 1250 calories of coconut oil, nut and seeds, veggie protein and cocoa powder. He’ll eat four of these every day. Combined with Alpineaire freeze-dried meals for breakfast and dinner, he aims to consume about 8000 calories per day.

What to Bring

Surviving on the ice in -30 degrees Fahrenheit and wind reaching 100 miles per hour requires specialized gear. O’Brady takes shelter in a burly Hilleberg Keron 3 tent that’s shaped like a tunnel. He stays warm while moving in a Mountain Hardwear Ghost Whisperer down jacket and Bergen of Norwayouter layers specifically built for Antarctica. His Garmin inReach satellite tracker sends his exact location to the inReach website at regular intervals (where you can follow his progress). He uses a satellite phone to check in every day and, if necessary, call for emergency pick-up.

All the gear and food gets packed in a carbon fibre sled called a pulk and dragged across on the ice.

Last-Minute Race

Louis Rudd is also attempting the same trip. Henry Worsley, who died in 2016 attempting the crossing, was a good friend of Rudd’s and got him into polar exploration. Rudd but planned on crossing the continent in the opposite direction but changed his plans after meeting O’Brady in Chile, agreeing to a long-distance race of sorts. Rudd started only 20 miles away from O’Brady.

Rudd has been to Antarctica multiple times, including a trip to Worsley’s last campsite with six comrades after his death. O’Brady has been training hard for the last three years as well. He completed a record-breaking 139-day Explorers Grand Slam (the seven summits and two poles) in May 2016, broke the 50 highest points record in the U.S., and dragged a sled around Greenland for a month in 2017.

Tune Outdoor’s new M1 Lite is a rugged, affordable, featherweight truck camper
Minimalist pickup owners will love the straightforward "everything you need, nothing you don't" design.

Sometimes less really is more. Personally, I think that's doubly true when it comes to camping. Whether you're backpacking, car camping, or RV'ing, there's beauty in a dead-simple camp setup. That's the thinking behind Tune Outdoor's new M1 Lite — a more affordable, more streamlined, and (wait for it ...) lighter version of the company's flagship M1 truck camper/topper.
While the original M1 is already lightweight and relatively affordable, compared to other overlanding and truck camping options in the space, Tune Outdoor is upping its game by making this new model even more affordable. That's done by cutting weight and overall size. The M1 Lite's interior is about 20% smaller, but that nets a 20-percent reduction in base weight. At a scant 322 pounds, it hardly weighs much more than some of the larger, most robust rooftop tents on the market. The result? Better fuel economy and a more agile ride both on- and off-road.

The compact interior features a smaller longitudinal double bed that measures 72 by 60 inches, compared to the M1's more generous east-west configuration. The over-cab space is also shorter, measuring just 45 inches. But the 57-inch-long alcove standard in the flagship M1 is available in the M1L as a $1,000 add-on. Overall, the space feels roomier than it should, though, thanks to a full-length pop-top roof with a generous 6.5 feet of headroom. That means most average-height adults can change and move around while standing. Panoramic, wraparound fabric "window" walls also help keep the space light and breezy.
The new M1 Lite starts at $8,999 (based on a Toyota Tacoma short bed). That's a full $4,000 cheaper than its OG predecessor, and Tune Outdoors will even install it for free at its Colorado headquarters. Eager buyers can reserve their very own with a $500 deposit to secure their place in line. First deliveries are expected sometime in December 2025.

The Pebble Flow travel trailer is packed with tech and ready to change vanlife forever
The future of RV'ing is bright, tech-forward, and all-electric for serious on- and off-grid camping.

It seems clear that the future of the world's vehicles is electric. As it turns out, running all our cars and pickups on dead dinosaur juice is only going to take us so far—literally. And the battery-powered revolution has begun in the RV industry, too, thanks in large part to the official drop of the all-electric Pebble Flow travel trailer.
California-based Pebble first announced its electric travel trailer back in 2023. Based on the long list of next-gen features and specs, I was stoked—tentatively, though, as vehicle manufacturers have a history of overpromising and underdelivering when it comes to concept announcements. I'm happy to report that the company has begun delivering its Flow Founders Edition, and everything we loved about the original seems to have come to fruition.

It's a 100% electric RV designed to move seamlessly between on- and off-grid camping, making it the perfect go-anywhere live/work/play space for modern nomads. Pebble promises up to seven days of off-grid camping, including full use of all onboard appliances. This is no small feat. RV owners who've tried to venture too far from the frontcountry know the struggle of keeping cool in the summer with a beastly, power-hungry air conditioner. But, it appears Pebble has finally solved this problem.
It's clear that Pebble put just as much thought into the interior design as well. The furniture is not only sleek, modern, and handsome, but the living quarters easily transform between office, bedroom, and lounge as needed. Panoramic windows with one-touch instant privacy glass envelop the space, creating a vibe that's bright, airy, and breezy. Tasteful ambient lighting and high-end finishes throughout elevate the look and feel well above the bargain basement vibe found in most "ordinary" RVs.

Wildfire forces closure of Grand Canyon’s North Rim for the season—and maybe longer
Grand Canyon National Park faces massive closures due to natural disaster

The Grand Canyon is one of the many areas currently affected by the Dragon Bravo Wildfire, which began last month. According to AZ Central, officials speculate that the fire began due to a lightning strike, which then spread rapidly due to sustained winds of 20 miles per hour, with gusts reaching up to 40 miles per hour. As of July 27th, 2025, the fire was still active, and the National Park Service reports that somewhere between 50 and 80 structures have been lost, including many administrative buildings and visitor facilities. Fortunately, they also report that no one has been injured, and no loss of life has been reported. Unfortunately, this devastating fire has closed the North Rim for the remainder of the season, and possibly longer.
