Julien Wanders and Sifan Hassan claimed the male and female 5km world records at the inaugural Herculis race in Monaco on Sunday.
Swiss runner Wanders recently beat Mo Farah’s European half marathon record, before taking the 5km record by a second, with a finishing time of 13:29.
The 22-year-old now holds the 5km world record, and the European record for 10km and half marathon.
Dutch runner Hassan, who already holds the European half marathon record, crossed the 5km finish line in a time of 14:44, beating the previous best set by American Sarah Pagano at 15:48.
The IAAF only recognised the 5km as a world record event in January 2018. Faster times prior to that are considered ‘unofficial world bests’.
The Herculis race forms part of the Monaco Run event, which took place on 16th and 17th February. Other events include a Pink Ribbon 5km Monaco Walk, 10km city trail and a 1000m race.
