So as things stand, I would assume that Emile Cairess and Phill Sesemann should be in a position to have their selection confirmed after this week's selection meeting.
A 3rd spot isn't out of the question if things can come together in London. Unfortunately I can't find a provisional entry list but perhaps best hope will be Mahamed Mahamed (2:08.40 Valencia '23) as I am assuming that Jonathan Mellor wont be doing another spring marathon after Seville.
On the women's side, I think there are 8 athletes with the standard - Charlotte Purdue, Calli Thackery, Rose Harvey, Clara Evans, Lily Partridge, Samantha Harrison, Natasha Wilson and Georgina Schwiening.
Assuming they are injury free, Purdue and Thackery will likely get the nod for early selection given they are about 3 minutes faster than the rest of the qualifiers.
Not sure if Jess Piasecki is looking to run the London marathon but she was another 2:22.25 in 2022 so is possibly another athlete who could challenge for a spot is she has recovered from injury.
