Looking ahead, Chelimo aims to run the 5000m in under 12:45 and compete at future Olympic Games. He also plans to focus on marathon running, having already finished third in his first half marathon at the New York City Half in March 2018.
In 2019, Chelimo was part of the pacemaking team for Eliud Kipchoge's sub-two hour marathon attempt in Vienna. Although not an official record due to race conditions, it was a unique experience for Chelimo.
