Nearly a year ago a man strapped himself down and completed 24 grueling hours on a Concept 2, rowing to honor his father’s memory and to raise awareness for gastric cancer. This year, again on February 12, what would’ve been his father’s birthday, Jason Miyagishima will be sitting down for another twenty-four hour tribute, this time on a Schwinn Airdyne.

As CrossFitters, we sometimes take on extreme and unusual challenges as part of daily training sessions. “Murph,” for example, is one of the more extreme and crippling workouts, calling for a total of two miles, 100 pullups 200 pushups, and 300 squats—all while wearing a 20 lb. weight vest for the Rx athlete. For the elite Games competitors, “Murph” took the fastest woman, Sam Briggs, 39:10 and the fastest man, Björgvin Karl Guðmundsson, 38:36.

Forty minutes is a very long workout, when we’re talking about CrossFit. Typical WODs will last 8 to 20 minutes. Many have 30 or 40-minute time caps, preserving the quality of production and protecting athletes from injury. So, to say that taking on a 24-hour workout is unusual would be quite an understatement. Taking on a 24-hour workout might even be considered insane; unless, of course, the reason behind the length of the effort is greater than the effort itself.

For the second year in a row, Jason Miyagishima is taking on 24 hours of sheer exhaustion to get attention—not for himself, but for the devastating effect that gastric cancer and other cancers can cause in families. Jason’s goal is to honor his father’s memory and to raise awareness and funds for CancerFit, ​Inc. ​and ​the ​Gastric ​Cancer ​Foundation by riding the new Schwinn Airdyne Pro.

His ride will take place at the box where he coaches—CrossFit RepScheme in Northridge, California. He will take his seat on the bike at midnight on February 12 and complete his ride 24 hours later. This year his goal is to surpass the money raised last year (he ​was ​able ​to ​row ​206,524 ​meters ​and ​raised ​$3,704). His goal is to earn $5,000, which he will split evenly between CancerFit, Inc. and the Gastric Cancer Foundation. Donations can be given online through his Mitsuo Strength Project website or in person at CrossFit RepScheme.  Also, each donation automatically enters you into a raffle with a chance to win a Marco Pro , WOD Gear clothing, and a Setwear Fitness belt.

Jason learned much last year during his 24 hour row, that will help him for this year’s event. Last year, the support of his community was inspiring. Friends and strangers joined him at all hours throughout the row, taking turns on the Concept 2 ergs that were lined up alongside him. A friend put out a tip jar that began as a silly gesture, but ended up netting hundreds of dollars. He remembers rowing last year and noticing after a number of hours had passed that the compression tights he was wearing were becoming loose. After testing his body composition, he discovered that he had, in fact, lost about 12 lbs. of bodyweight, most of it in lean body mass.

Like last year, Jason has done some testing in which he completed one hour and three hour sessions to compare the difference between long rows and long rides. He has a background in mountain bike and motocross racing, so he’s not unfamiliar with long periods of time on a bike. This training and preparation will be keys to his success, as will his improved plan for fueling. The power of the long row to change his body composition got his attention, so Jason plans to increase his intake of carbohydrates to provide his body the energy it needs to sustain both his lengthy efforts and his muscle mass.

Knowing the punishment of 24 hours of nonstop rowing, why would he now undertake what most people would agree is a more difficult challenge? When asked, Jason laughed and replied, “I just like to torture myself.” He remembers the original Airdyne of the ‘80’s. “We called it ‘Satan’s Tricycle’ or ‘The Devil’s Bike.’ This was the bike that started it all. It’s not uncommon for people to complete 24 hour rows.” In talking with Schwinn, he realized that this is something that no one has really done, which fueled his desire to complete a long ride.

One thing is clear when talking to Jason; he’s passionate about life, family and reaching out to the community. Follow and support his efforts by visiting and donating through or by visiting and riding alongside Jason at CrossFit RepScheme on February 12.
