Early career Kiprop had her first win in a European road race in
Nogent-sur-Marne in 2005, running 32:55 minutes at the local
10K run. She began training with GS Valsugana Trentino, an athletics club in
Trento, Italy, and made a successful
half marathon debut in September 2005, taking third place at the high profile
Lille Half Marathon with a time of 74:02 minutes. She ran for the club in
track races in 2006 and 2007, but did not have the same levels of performance as she did on the roads. She won the
Corrida di San Geminiano 15K race in 2007. She returned to Kenya in 2008 and at the end of the year won the
Tuskys Wareng Cross Country. A series of road victories came in 2009. A personal best of 69:29 minutes to win at the
Nice Half Marathon ranked her in the top forty for the event that year. She won at the
Merano-Lugundo Half Marathon, the
Cuneo Run and the 10K de la Provence in
Marseille. Kiprop was mainly a runner-up in 2010, starting at the
Alicante Half Marathon, then the
Paderborner Osterlauf,
Hambaurg Alsterlauf and
Singelloop Utrecht. She won the
Poznan Half Marathon and the
Sotokoto Safari Half Marathon, as well as setting a personal best 32:20 minutes to win a 10K in
Oelde. She did not compete in 2011. A win at the
World Bangalore 10K followed a month after. In June she won the
Zwitserloot Dak Run in a best of 31:44 minutes and was the victor at the
Zwolle Half Marathon. A close third at the
Delhi Half Marathon in November was her last big road race that year.
Marathon running The 2013 season marked a career breakthrough for Kiprop as she achieved new personal bests and ran in her first major
marathon race. She began the year with a win at the
Egmond Half Marathon. The
RAK Half Marathon proved to be a very fast race, with four women under 67 minutes – Kiprop's personal best time of 67:39 minutes for sixth place was the fastest ever recorded for such a low position. She set out to win at the Berlin Half Marathon, taking an early lead, and was first to finish in 67:54 minutes, reversing her placings with Ongori from the previous year. Her fast performances earned her an invite to the
2013 Berlin Marathon and on her debut run she recorded a time of 2:28:02 hours for the distance, ending in fourth place in the top level competition. Her last outing that year was at the first ever
Kochi Half Marathon, which she won. Kiprop was among the leaders at the 2014 RAK Half Marathon, but fell behind the eventual winner
Priscah Jeptoo and finished fourth in 68:36 minutes. At the 2014
Seoul International Marathon, Kiprop topped the podium in the classic distance for the first time. Her run of 2:27:29 hours was a personal best and enough to fend off
Ashu Kasim in the final kilometres of the race. She was coached by her husband, Ugandan
David Marus. In 2017 Kiprop competed in the
marathon at the
2017 World Championships held in London, placing 7th in 2:28:19. ==Achievements==
