Mark your calendars, the February 19th race is something athletics fans can get excited about. The marathon WR holder Brigid Kosgei vs. the half marathon WR holder in Ababel Yeshaneh headline the women's race. For the men, we get a replay of gold vs silver from World Half in Jacob Kiplimo vs. Kibiwott Kandie. Every time Yeshaneh and Kosgei have raced so far, one of them has broken the WR. And Sara Hall of the US is making the trip.
