Plan is the same for every sprinter in Australia except for Sally Pearson: keep on competing through to the Ausdtralian national championships in mid-April. Unfortunately the nationals are also in Melbourne where by mid-April the weather can be very cold and pretty feral - gee, come to think of it, just like it was at the Trials last weekend!
There will definitely be a men’s 4x4 relay team nominated for London to the Australian Olympic Committee whose team it ultimately is. The AOC will decide on the way they see the merits as to whether to endorse Athletics Australia’s nominations to the relay. But the selectors did not name anyone to the relay - not even John Steffensen, the only man to date with even an Olympic B-qualifying time to his credit. The selecftors will meet again on June 7 to reflect on performances at the Nationals and presumably then will name names. Therefore the only option is for Olympic hopefuls to reload and reset for the run up to the Nationals and hope that, without the artificial and inappropriate constrictions of having to compete in three obligatory meets (Adelaide, Perth & Sydney, plus the Trials in Melbourne) they and their coaches can properly plan to train and race when it suits the individual. One thing though is that they dare not leave their qualifying time effort for the Nationals due to the likely poor weather conditions. They need to regroup and take a crack at a fast one within the coming four weeks, imho.
