Switzerland's Schär, a marathon winner at Boston, London, Chicago and New York since 2017, clocked 53.10sec to finish clear of Tatyana McFadden of the United States - seven times a Paralympic champion, 13 times a world champion and multiple major marathon winner - who clocked 54.51.

Third place went to Germany’s Merle Menje in 56.65, with home wheelchair racer Alexandra Helbling fourth in 57.42.

Britain’s Samantha Kinghorn earned her fourth win at the Grand Prix following earlier successes in the T53 200mm, 800 and 100m events.

Kinghorn won the T53 400m title in 55.55, ahead of Switzerland’s Catherine Debrunner, who clocked 56.47.
