After training in the mountains of Kenya for the past year, Shadrack Kosgei, 28, had no problem running over three bridges during Saturday morning’s Allstate Life Insurance 13.1 Miami Beach Half Marathon, which began and finished at South Beach.

Unlike many in the field of 2,574, Kosgei didn’t struggle at all while climbing two bridges along the Julia Tuttle Causeway at miles 4 and 5, and another one at mile 10 on the McArthur Causeway, on the way to a win in 1 hour 3 minutes 14 seconds that earned him $13,100. By maintaining a pace of 4:50 per mile in clear and dry 58-degree weather, Kosgei, a captain in the Kenyan army, was able to pull away from Philemon Terer, 27, a resident of New Mexico, as the two descended the last bridge.

Despite a strong finishing kick along a winding ocean front path inside Loomis Park, Terer fell 10 seconds short, and finished runner-up, which was good enough for a $1,000 pay check. Also taking home money was Tumicha Horso, 32, a resident of Washington.

“I like going up and down because it’s easy for me,” said Kosgei, a father of three. “I knew I was going to win when I made my move.”

Defending women’s champ Risper Gesabwa, 23, a resident of Marietta, Ga., finished in 1:12:15, 5:07 better than last year. The winner of January’s ING Half Marathon also collected $13,100 with Saturday’s win. Tsehay Gebre, 20, of New York, won $1,000 by finishing second in 1:14:19.

Saturday’s race was the final event in an eight-race series that began last March in New York. The race began at 13th and Ocean Drive and finished inside Loomis Park at 7th Street. The course took runners on one big loop across the Julia Tuttle Causeway, then south before heading back across the McArthur Causeway.

The event featured an adjoining Karhu 5K race that started 15 minutes after the half marathon 6:30 a.m. start. Taking first in the field of 533 runners, Jorge Grajales, 21, of Miami, was the winner in 16:25, his second big victory since winning the Tropical 5K in January. Ryan Trombly, 38, of Miami Beach, came in second.

The female winner was Sadie Wells, 33, of Miami Beach, in 19:08. Runner-up was Stephanie Ingalls, 24, of Surfside (19:19).
