Now we have three men with a great opportunity. Jeff Riseley has, at the age of 34, come into form at just the right time to qualify, after years of injury and indifferent form. He ran well for 4th in his heat in 1.45.41, coming home hard and passing a former world champ, Pierre-Ambroise Bosse. 
West Australian Peter Bol has broken the Australian 800m record at the Tokyo Olympics. Running in heat 1, Bol sat in second for most of the race, and finished strong crossing the line also in second.  Easing up over the line, Bol still managed to break the Australian 800m record clocking 1:44.13.  Not hard to see Bol dipping significantly under 1:44.00 in either the semi-final or final.

Sifan Hassan is potentially about to have a crack at the impossible treble; the 1500m, 5000m and 10,000m at the Tokyo Olympics. There is still a possibility that she will scratch from one event (rumoured to be the 1500m), but for now Hassan's name is on the start-lists for all three.
