The Weltklasse Zurich. Coverage of the 11th meeting of the campaign, held at Letzigrund in Switzerland. Many of the stars of the recent World Championships are expected to be in action, and it was two of the planet's leading sprinters who took the headlines last year, with Noah Lyles winning the men's 200m in a meeting record of 19.52 second and Shelly-Ann Fraser-Pryce equalling the mark of 10.65 set by Elaine Thompson-Herah a year earlier in the women's 100m.
