Josh Kerr's bid for the mile world record is officially set, as the Scottish runner was announced among a stellar international lineup for Saturday's Diamond League event at London Stadium.
Compatriot Neil Gourley, the European indoor mile record-holder and 2025 world indoor silver medallist, will also compete in the historic Emsley Carr Mile.
Joining the 28-year-old Olympic silver medallist and two-time world indoor champion are Paris Olympic bronze medallist Yared Nuguse, along with fellow Americans Hobbs Kessler and Nathan Green.
Jake Wightman, last year's world 1500m silver medallist, will feature in one of the strongest 800m fields in recent years.
The Scot aims to build on his performance in Friday's Diamond League meeting in Monaco, where he finished a close second to Kenya's Emmanuel Wanyonyi as the Olympic and world 800m champion broke the long-standing men's 1,000m world record on his debut at that distance.
Wanyonyi joins Wightman in London, alongside Olympic silver medallist Marco Arop of Canada, Olympic finalist Bryce Hoppel of the US, Ireland's Mark English, and English duo Max Burgin and Ben Pattison.
Olympic champion Keely Hodgkinson leads a strong English contingent in the women's 800m, joined by world silver medallist Georgia Hunter Bell, in a race that also features the Netherlands' Femke Broeders-Bol, who has stepped up from the 400m hurdles.
Julien Alfred heads to London after a blistering run in Monaco, where the Saint Lucian clocked the third-fastest women's 200m time in history. The double Olympic medallist will defend her London title against a world-class field including American Gabby Thomas and English trio Dina Asher-Smith, Amy Hunt, and new British champion Success Eduan.
