new African record, with the previous record of 1:06:44 hours set by Elana Meyer of South Africa in 1999. Keitany also beat the previous Kenyan record of 1:06:48 that she set in Udine two years earlier. The director of the New York City Marathon, Mary Wittenberg, suggested that she could become a world-beater over the full marathon distance in the coming years. 2010 She won the Abu Dhabi Half Marathon. She also won the Berlin 25 kilometre race, setting a new world record of 1:19:53 hours. The previous record was set by Mizuki Noguchi of Japan in 2005. Keitany finished almost five minutes ahead of runner-up Alice Timbilili. In preparing for the New York City Marathon, she won the Portugal Half Marathon in Lisbon in September, leading from the front to win largely uncontested in a time of 1:08:46. In her debut at the New York City Marathon, she was among the leading three for much of the race but faded to finish third in a time of 2:29:01 hours. 2011 Keitany began the year in record-breaking form as she won the Ras Al Khaimah Half Marathon with a world record time of 1:05:50 hours. This marked the first time a woman had run the distance in under 1:06 hours on a non-aided course. She also set other records along the way, including a world record of 1:02:36 for 20 kilometres and world best times for 8 kilometres and 10 miles. She then won the London Marathon in a time of 2:19:17, pulling away from the field at the 14-mile mark and becoming the fourth fastest woman ever over the marathon distance. In September, she won the Portugal Half Marathon for the second time and improved upon her own course record with a winning time of 1:07:54 hours. She was the pre-race favourite for the New York City Marathon, where she built a significant lead by the halfway point (running at more than four minutes faster than the course record). She slowed dramatically, however, in the second half of the race and was overtaken by Firehiwot Dado and Buzunesh Deba, leaving her in third place with a finishing time of 2:23:38 hours. 2012 She intended to improve her world record mark at the Ras Al Khaimah Half Marathon, but windy conditions slowed her to a finish time of 1:06:49 hours. At the London Marathon, she broke Catherine Ndereba's African record
