CNN —The US Olympic Marathon Trials will be held in Orlando, Florida, on Saturday – an opportunity for runners to book a place at the Games in Paris later this year. Here’s what you need to know ahead of what is regarded as one of the most exciting, unpredictable events on the American running calendar. Conner Mantz and Clayton Young are the only two men to run under the Olympic standard time of 2:08:10, both having done so at last year’s Chicago Marathon. Defending trials champion Aliphine Tuliamuk is looking to make back-to-back Olympics having run 2:24:37 in Boston last year. In previous marathon trials, it was simply the top three men and women who qualified for the US Olympic team.
