Does anyone know anything about her coach and manager?
I think Andrew Butcher has improved more than Laura Muir.
Andrew's 5k time is still not a 12:54 (e.g. Dieter Doper Baumann …who was probably doing EPO in 1992 when he won the Olympic 5k…but nobody can prove it. There was no EPO test until 2000.)
The idea of using how people "look" as a criteria is silly.
