It doesn’t mean anything. Records fall everyday…BFD.
Look at the 3 Oregon kids go 3:50, 3:50, 3:53 indoors in a team meet and Ben True set his 10K PB by 0:26 at age 35 and tell me the new track shoes aren’t shifting the line. Whether that’s a problem to be regulated or not is a debate for others, just like with the swimming speed suits, but it cannot be denied that the shoes are impacting the times.
