There will be hopes for double Kenyan delight in men's 800m and women's 1,500m through Emmanuel Wanyonyi and Faith Kipyegon at the world championships in Tokyo that get under way on Saturday.
Despite having contested only three official races this year, albeit one in a world record time, Kipyegon is fancied to win a fourth world 1,500m title and draw level with Moroccan legend Hicham El Guerrouj.
