In the third of three heats of the M40 short hurdles today at Linz worlds, French Olympian Vincent Clarico clocked 7.95 seconds, nipping American Karl Smith’s world record for the 60-meter event of 7.96, set in 2000 and tied by Clarico a month ago. But America got a record back when Dexter McCloud (also in the third of three heats) ran the 39-inch hurdles in 8.35 — and lowered the listed M45 world record of 8.36 set by Colin Williams of the USA in 2002. Thank goodness we don’t have worry about wind readings indoors — unless the collective gasp of amazement is counted. Tomorrow is the last day of the WMA world championships, with who-knows-what delights in store.
