His fastest times for some standard distances are 3:42.29 for 1500 m, set in 1998; 13:11.77 for 5000 m, set in 2000; 27:13.98 for 10,000 m, set in 2001 (an American record which stood until 2010); and 2:08:37 for the marathon, set at the 2014 Boston Marathon.
On October 11, 2010, he released his autobiography, Run to Overcome, which was published by Tyndale House Publishers. The book, co-authored with noted sports writer Dick Patrick, included recollections about major milestones in his life, such as his Olympic competitions and other running highlights, as well as his early years, leading up to the present day. He is also the driving force behind the MEB Foundation, the "MEB" standing for "Maintaining Excellent Balance," which principally promotes healthy living, and other positive lifestyle choices and motivation for school-age youth.
On April 21, 2014, Meb became the first American man to win the Boston Marathon since 1983, besting many of the heavy African favorites in a new personal best of 2:08:37. With this victory, Meb becomes the only Marathoner in history to win the Boston Marathon, the New York Marathon, and an Olympic Medal.
Keflezighi broke his hip during the 2008 U.S. Olympic Marathon trials in Central Park. He finished in eighth place and did not qualify for the team. During the race, his friend and training partner Ryan Shay died of a heart attack.
He won the 2009 New York City Marathon, setting a personal best of 2:09:15. Keflezighi was the first American to win the marathon since 1982.
On April 19, 2010 he ran his third fastest time of 2:09:26 while finishing 5th in the 114th Boston Marathon, despite training at half his usual mileage with a knee injury. He ran with the leaders for much of the race, before slowing at the finish.
He ran the San Jose Half Marathon as part of his preparation towards a New York title defense and he comfortably won by a margin of three minutes, finishing in 1:01:45.
On January 14, 2012, he won the U.S. Olympic Marathon Trial in Houston with a time of 2:09:08, which was a new personal best by 5 seconds. He is the oldest winner of the Olympic Trials Marathon at age 36.
On June 22, 2013, Keflezighi finished second in the US Half marathon Championships held around Duluth, Minnesota in 1:01:22.
On April 21, he won the 2014 Boston Marathon, the first American male to do so since 1983, and first American since 1985, with an official time of 2:08:37. The race was two weeks before his 39th birthday, making him the oldest winner of the Boston Marathon since at least 1930.
Keflezighi uses nine-day training cycles instead of traditional training weeks, which he says allows him to concentrate on training while also allowing himself to recover. His training is composed of tempo runs, intervals, long runs and cross-training. In the weeks leading up to the 2014 Boston Marathon, he ran 2-3 times a day, and used his ElliptiGO for 10-20 mile cross-training rides to avoid injuries. Additionally, he tries to keep himself healthy with daily core-strengthening exercises, stretching, altitude training, tune-up races, and a high-protein diet with 5 servings of fruit.
In 2011, Sony released a special-edition Meb Keflezighi 2GB W Series Walkman MP3 Player. It came pre-loaded with audio tips, along with a booklet containing tips on running, nutrition, stretching and more. The product is now discontinued.
On July 2, 2014, a limited-edition ‘Meb 8S’ ElliptiGO was released to commemorate his 2014 Boston Marathon victory. The bike features his motto “Run To Win” and his signature, along with a patriotic-themed paint job.
He is represented by his brother Merhawi, who as a UCLA undergraduate was a student manager for the Bruin men’s basketball team (head student manager in 2001-02) and is a 2006 graduate of the UCLA School of Law. Meb and his wife Yordanos married in November 2004 and have three daughters – Sara, Fiyori and Yohana.
