Merrell Team | August 07, 2018

ROCKFORD, Mich. (Aug. 7, 2018) —  Merrell Ambassador and Endurance Athlete Jason Antin and Endurance Athlete Erik Sanders have set the new fastest known time of the Rainier Infinity Loop: 59 hours and 21 minutes. The previous fastest known time was 66 hours and 22 minutes, set on June 25, 2018 by Scott Bennett.


Starting the journey on Tuesday, July 10 and commencing on Thursday, July 12, the Rainier Infinity Loop challenged Antin and Sanders by providing an all-encompassing, ultra-mountaineering adventure. The trek entailed 135+ miles and 47,000 feet of vertical gain. The Loop summits Mt. Rainier twice, and runs the entire iconic Wonderland Trail in Rainier National Park.


“I’d been inspired by the thought of completing the Rainier Infinity Loop for months prior to us setting out,” said Jason Antin. “This proved to be one of my most challenging and memorable experiences to date. I’m thrilled to be able to share our journey with others and hopefully inspire them to take on outdoor challenge of their own.”


Wearing a variety of Merrell footwear and apparel, Antin’s full gear list can be found on his website. For the first 30 miles of trail, Antin wore Merrell’s latest trail runners, the Agility Synthesis Flex. Key technologies that made this a successful choice for the adventure include FLEXconnect™ technology with a Hyperlock™ heel for security during descents and sharp turns. M SELECT™ Grip+ provides an outsole that’s durable and highly slip-resistant over mixed terrain. Dual directional flex grooves in the midsole add agility and stability while sticky, anatomical lugs provide superior traction. The Agility Synthesis Flex are now available on in men’s and women’s sizes.


Jason Antin, a native of New England who now calls Colorado home, focuses all of his time striving to achieve the ultimate work-life balance. Beyond helping launch a handful of outdoor focused start-up companies, Jason spends much of his time working as a technical Mountain Guide for Denver Mountain Guiding, and also as a strength and condition coach at The Alpine Training Center in Boulder, CO where he prepares his athletes for the physical and mental rigors of the mountains. Off the clock, Jason shares his home in Golden, CO with his wife Jenny and 2-year old daughter Avery. He enjoys moving quickly in the mountains over all mediums that mother nature shares with us whether that be trails, rock, ice or snow.


Erik Sanders is a multi-sport athlete also living in Golden, CO. Over the last ten years he has participated in some of the world’s most brutal Adventure Races. He enjoys moving efficiently in the natural world and is inspired by human-powered efforts that push the mind and body into the unknown. Erik works in the telecom industry as an engineer and manages a crew of field engineers. With a lot of time spent traveling to remote work sites, he is able to combine his passion for adventure and the outdoors. All of this adds to the type of life Erik seeks to experience - from traveling, to racing, to simply moving in the mountains.
