My focus in 2016 will be the IAAF World Indoor Championships in Portland, and as preparation for that, I will try to break the world indoor mile record in Stockholm on February 17.
I had a great season and truly enjoyed competing around the world - from Monaco, where I managed to establish a world record, to Beijing, where I finally captured my first world outdoor title.
I find outdoors easier than indoors, but I am more interested in indoor athletics. I prefer it because it is hotter indoors, and I like the shorter laps.
