Mariska Kramer Postma didn't look like the typical jubilant marathon winner Sunday as she crossed the finish line at the 2014 Life Time Miami Marathon. Kramer Postma swatted at the finish line tape in disgust because her winning time of 2:49:28 missed her target in the race by 11 minutes. When you are winning South Florida's elite distance race for the second year in a row, and overcoming a pre-race stomach flu on top of it, you have a right to be picky about your time. “There simply was nothing in my legs, no energy," said Kramer Postma, a native of the Netherlands. "I had to talk to them like ‘Hello!’ Kramer Postma's legs serviced her well enough as she and Kenyan Samuel Malakwen, the 2012 winner who pulled away from Julius Choge in the final five miles, became the first two-time Marathon winners in an event which began with less than 4000 runners 12 years ago and sold out at 25,000 runners for the third consecutive year. Malakwen was one of four Kenyan men to enjoy top finishes Sunday. In the Half-Marathon, Edward Tabut (1:06:45) won by nearly two minutes over countryman George Towett (1:08:30) while Cesar Cedeno (1:08:50) of Costa Rica came in third. Shannon Miller, who lives in Bronx, NY, won the women’s half marathon (1:21:08) with Yolymar Pineda (1:22:00) of Venezuela second and Miami’s Angelo Brito third (1:22:38). It was the first year the race was produced and presented by Life Time – The Healthy Way of Life Company (NYSE: LTM), which recently acquired US Road Sports. Eighty countries and all 50 states were represented in the field, with a particularly strong contingent coming from South and Central America and the Caribbean. The event has evolved into a significant tourism boost for South Florida with an estimated $55 million economic impact. Nearly 55% of the runners arrived for the race by air, and they also brought along an estimated 11,000 support spectators.
