Micheal Day is a professional American “Current School” Bicycle Motocross (BMX) racer whose prime competitive years are from 2002–Present. His nickname is a play on a common phrase. Mike Day’s official Union Cycliste Internationale (UCI) number, which was originally assigned to him by the American Bicycle Association (ABA)1 (not affiliated to the UCI), he requested for it from and is assigned it by the UCI for life regardless of how he does in a race season, is #365. With the exception of quadrennial leap years, that is the number of days in a calendar year. As a result, a play on his surname “365 Day” occurs from the common phrase “…365 days a year”
(alternatively “..365 days per year”):
“When you turn pro, they always give you a number in the 300s,” he said, “and with my name on the back, it said: 365 Day. Everyone talked about it, and I said, ‘That’s it. That’s going to be my number.’ I’ll pretty much wear it till I’m done racing.”
On June 14, 2008 Mike Day won a place on the USA BMX Olympic Team by winning the Team Trial at the Olympic Training Center in Chula Vista, California. This team will represent the USA in the first ever BMX racing competition in the 2008 Summer Olympics in Beijing, China with Teammates Kyle Bennett, Donny Robinson, and Jill Kintner. As of August 20, he has made the Semi Finals in the 2008 Summer Olympics, winning both the Seeding Run time trials and was the overall winning of the three runnings of his Quarter Finals, sweeping all three. On August 22, Mike Day won the Silver medal in the Men’s BMX Final at the 2008 Summer Olympic Games. Since the Men’s Final was raced after the Women’s Final in the sport’s debut games, he is the second American ever to win a medal. However, he is also the highest placing.
