Lausanne

Olympic 100m champion Noah Lyles headlines a stellar list of athletes seeking perfect Swiss timing as they build up to next month’s season-ending World Championships.

American Lyles goes head-to-head with Kishane Thompson, the Jamaican he beat by just five thousandths of a second to earn Olympic gold a year ago. Leading Brits in action include Olympic medallist Georgia Hunter Bell in the 800m and former world champion Dina Asher-Smith in the women’s 200m alongside Jamaica’s Shericka Jackson, the second-fastest woman in history.
