'I am very grateful. This is the first gold medal for Kenya (at Rio 2016).'
'It was very hot but everybody had to get through the heat. I had to control my body and listen to my body very carefully.'
'I had prepared that I would move out at kilometre 35 and my body was responding very well, as well as my movement.'
'I was in Beijing but I was pretty disappointed that I wasn't able to win a medal or make it on the podium, but I knew one time, one day, I'd be somewhere. I'm so happy, I feel extremely proud. I can't even explain what I'm feeling.'
'I was never worried that I'd lose this. At the 40km I knew the gold was mine. At 35km I noticed that my other two teammates had dropped off and that gave me the motivation to carry on. At 40km I saw there were three of us but I knew whatever happened I couldn't lose the gold and then I knew I was on the way to history.'
