The 2019 Athletics World Championships have arrived in Doha, with the planet's finest athletes set to compete over ten days.
At the last World Championships, in London two years ago, there was just one new world record set, as Portugal's Ines Henriques smashed the men's mark in the 50km race walk.
However, this year already, US star Dalilah Muhammad has set a new world record in the 400m hurdles, while Karsten Warholm has his eyes on the men's equivalent.
Sprint sensation Noah Lyles has chosen to target the 200m, and has even spoken about having a crack at Usain Bolt's world record, while the Netherlands' Sifan Hassan broke the mile world record earlier this season and looks set to run in the 10,000m, as well as either the 1500m or 5,000m.
