Dina Asher-Smith beat Olympic champion Elaine Thompson and world champion Dafne Schippers to claim victory in the Diamond League 200m last night in Stockholm.
Inside Muirs food and training diary BBC Sport after the event, Asher-Smith said, “I'm really happy. I wasn't anticipating the time that I ran. In these conditions and at this time of the year, it's really good.
"The World Championships are a very long time away. While it's good to be in good shape now, it's important I stay in good shape and continue to progress. I need to run faster by September because I know everyone else will too."
