Triple triumph for dominant US as Johnson-Thompson sets up bid for gold

• McLaughlin-Levrone stars on thrilling night in Paris
• Johnson-Thompson leads heptathlon after day one

Sydney McLaughlin-Levrone led a triumphant night for US athletics by beating her own world record in the women's 400m hurdles and further golds at the Paris Games went to Americans in the women's long jump and men's 110m hurdles.

The sheer power of the 25-year-old McLaughlin-Levrone in the Stade de France made it appear as if she had run the race at a canter but the US star was never in danger of being caught, and improved on her best with a time of 50.37sec.
