Joyciline Jepkosgei broke the world 10km record* at the Birell Prague Grand Prix, an IAAF Gold Label Road Race, on Saturday (9).
The 23-year-old Kenyan clocked 29:43 to smash through the 30-minute barrier and break her own record of 30:04, also set in the Czech capital, at the Sportisimo Prague Half Marathon on 1 April. The performance marked the fifth world record of the year for Jepkosgei, who broke four --10km, 15km, 20km and the half marathon-- en route to her victory at the Prague Half Marathon.
