Growing up in Cypress, California, where he was home-schooled through high school, Blatchford started his cycling career at age thirteen, when he first discovered the now-defunct Olympic Velodrome that hosted the track cycling tournament at the 1984 Summer Olympics. Blatchford's visit and fascination had thereby inspired him to become a track sprinter, and eventually claimed the silver medal at the 2004 UCI Junior World Championships in Los Angeles. On that same year, he outclassed Giddeon Massie and Christian Stahl for an elite U.S. national title in men's sprint that officially marked his debut as a force to be reckoned with on the domestic and international track cycling scene. Shortly after his early success, Blatchford became one of the resident athletes of the U.S. Olympic Training Center in Colorado Springs, Colorado. His sporting career continued to flourish with a bronze medal in men's sprint at the 2006 UCI World Cup series in Los Angeles, followed by an impressive, gold medal effort for the U.S. cycling team at the 2007 Pan American Road and Track Championships in Valencia, Venezuela. With an aim on the team sprint event for the Olympics in 2008, Blatchford teamed up with Olympians Massie and Adam Duvendeck to set a new U.S. record of 45.128 seconds at the UCI World Championships in Manchester, England. Following a stunning performance from the World Championships, Blatchford qualified for two track cycling events at the 2008 Summer Olympics in Beijing by recording the fastest entry time, and earning an automatic berth from the USA Cycling Team's Selection Camp. In the men's team sprint, held on the first day of the track program, Blatchford helped his teammates Massie and Duvendeck set an eighth-place time in 45.346 on the morning prelims before they were knocked off by the Brits in the first round. Two days later, in the men's sprint, Blatchford lost his round-of-sixteen match-up against France's Kévin Sireau, and finished second in his repechage heat behind Japan's Kazunari Watanabe, thus eliminating him from the tournament. Earlier in the morning session, Blatchford grabbed a fifteenth seed with a time of 10.470. In 2009, Blatchford immediately took up a two-year sabbatical from the sport, when the U.S. cycling team disbanded the sprint program in track cycling. By early 2011, he came out of an early retirement to join with four other riders for Project London 2012, an elite track cycling team, inspired and created by Rubicon Cycling LCC, that fosters the youth to become champion professional athletes, fulfilling their dream to represent the United States at the Olympic Games. Returning from two years off the sport, Blatchford managed to reclaim the men's sprint titles at the 2011 U.S. Track Cycling Championships, and further continued his stellar ride as part of the team that registered an American record of 44.036 and earned a silver medal at the Pan American Games in Guadalajara, Mexico. Having been chosen by USA Cycling to be eligible for team selection, Blatchford sought his official bid to compete for the 2012 Summer Olympics, but he was shortlisted.
