Cheprot made a breakthrough at the 2013 Roma-Ostia Half Marathon, finishing third behind world champion Wilson Kiprop with a time of 59:20 minutes. This moved him to seventh in that year's rankings. Better results did not materialise late rin the year, however, as he failed to complete the Rome City Marathon and was three minutes slower than his best at the Portugal Half Marathon, coming sixth. A fourth-place finish at the 2014 Roma-Ostia earned him his first international call-up and at the 2014 IAAF World Half Marathon Championships he placed 22nd overall. He also managed a 10K best at the Prague Grand Prix that year, recording a time of 27:41 minutes which again ranked him in the world's top ten for the season.
