I know that it's more a case of the 800m standards being unfathomably bad for a number of years, but why have the times suddenly improved so markedly? And not just at the top end. There are already more sub 1:45 guys this year than in the entire previous seasons.
Are guys just forcing each other to up their game? The super shoes suddenly working for the 800m? Or something more sinister?
TBH, it reminds me of 83/84 when HGH came out and suddenly so many guys (particularly American based) were running 1:43.
