I've rewatched the mile start in slow motion. The first offender is Ciattei, who for some reason spreads both his arms wide as if he's showing off his wingspan, this happens within the first 9m of the race. This prompts Giles to do the same but in a more aggressive manner, basically shoulder barging Hoare, a miracle Hoare didn't fall.
All while this is happening, Laros is going out extremely fast to get to the front (fair call considering what happened in Monaco). Unfortunately for him, Giles looks to his left for some reason?? and runs straight into the back of Laros. This causes Laros to fall, followed by Gourley.
Gourley ends up impeding McSweyn and Spencer and Davies (pacer) who have to run wide to avoid him. The next camera angle from above shows McSweyn in lane 5 and gapped from the field. I'm surprised he was even able to get to the front after that.
Mills was the 3rd victim as he smoothly jumped over Laros, only to have a barrel rolling Gourley in front of him and smashes right into him. I really hope Gourley is okay as he was mid roll, about to find his footing and get back up before Mills full speed off a jump slams his knee/foot straight into his stomach, knocking Gourley back down again.
At this point, the race is well under 50m in, 3 runners have hit the deck and almost half the field have been heavily impacted by this scuffle (Laros, Gourley, Mills, Hoare, McSweyn, Spencer, Mechaal).
It's absurd the officials did not recall the race??? At 15.5 seconds on the counter, Gourley and Mills can both be seen on their feet, raising their arms in frustration towards the officials to recall. These officials should have immediate recognised the issue and fired the gun to recall. Especially after Gourley and Mills are calling for it, with the race having barely passed 100m at that point.
Really disappointing circumstances for most of the runners. It's great to see Hoare tactically execute the race well but the organisers need to do better. At the very least, Giles and Ciattei need to be sanctioned for their actions. Giles seemed to be the more aggressive one of the two and should be DQ'd.
