World half-marathon record-holder Joyciline Jepkosgei is set to make her marathon debut at the Honolulu Marathon on December 9. The Xinhuanet News site reports she chose Honolulu in order to keep her debut low-key. She was invited to run the Valencia Marathon on December 2, but declined. The Kenyan runner set the world record at the Prague Half-Marathon in September 2017.
2017 was an astonishing year for Jepkosgei. Not only did she break the world record in the half (in 1:04:51, the first time a woman has run sub-65), but her 10K, 15K and 20K splits were also faster than the current world records in those distances. Later in the year, she broke her own 10K world record, becoming the first to run sub-30, also in Prague.
This year, Jepkosgei finished second at the Manchester 10K (which was won by Ethiopia’s Tirunesh Dibaba), and third at the Great North Run in Newcastle, UK, with a time of 68:10.
