Career
In her first marathon outing in Europe, she came third at the 2007 Dublin Marathon with a time of 2:33:27 hours. She was runner-up at the Reims Marathon later that year behind Agnes Kiprop. Kiyara broke another course record at the 2010 Maratona di Sant"Antonio in Padua, improved her best further with a finish of 2:30:19 hours.
She made a step up at her first top level marathon race in October 2011, as she knocked nearly five minutes of her former best with her fourth place performance of 2:25:23 hours at the Eindhoven Marathon.
At the 2012 Hamburg Marathon, Kiyara appeared to have taken the biggest victory of her career, winning in a course record and personal best time of 2:23:47 hours. However, she tested positive in the post-race drug test for norandrosterone - a metabolite of the anabolic steroid nandrolone - and was banned for doping for two years.
Her period of ineligibility from athletics competition expired on 18 July 2014.
