By day, Chris Solarz analyzes hedge funds for big pensions, endowments and other clients of investment consulting firm Cliffwater. By night—and early mornings and weekends—Solarz is a serial world record setter in tests of extreme endurance.
The 35-year-old's latest feat was to set the Guinness World Record for the greatest distance run in 12 hours on a treadmill by logging an astounding 77.07 miles.
Solarz did it on Jan. 18 in Edgewater, New Jersey at the Fitness Factory Health Club from 7:00 am to 7:00 pm. The rules were simple: Run at any speed and take as many breaks as desired, but the clock never stops.
"This was the most physically demanding of all of my six Guinness records," Solarz said. "I knew that the record was just within my reach but I would need to get in the best shape of my life. After I put in 150 mile weeks for two months, I knew I could do it, but I still needed to execute. I had a perfect day and ended up breaking the record less than seven minutes before the 12 hour mark!"
He beat the prior record of 76.68 miles set in 2013 by Eusébio Bochons in Switzerland. Solarz did not leave the treadmill for the entire 12 hour period and ran at an average pace of 9 minutes and 20 seconds a mile.
To sustain himself, Solarz ate more than 5,000 calories worth of bananas, hummus wraps, granola bars and sports drinks. He was supported throughout the day by his wife, one-and-a-half year old son Sebastien, and "dozens of friends and family members" who alternated running on adjacent treadmills, according to Solarz.
The new record is nothing new for Solarz. He has run more than 200 marathons and ultra-marathons in 38 countries around the world, including six 100 mile races. He currently holds five Guinness records: Two for marathon running (both group and as an individual); one for stair climbing (going up 33,000 feet in less than 12 hours); one for subway riding (hitting all 468 stops on the New York City system in less than 23 hours); and one for beer drinking (visiting 250 bars in 24 hours).
That's all good. Because in the world of hedge funds, endurance is the name of the game.
