I agree, but it's one of those many situations in which you can deceive yourself into thinking that whatever you've just heard conforms to the strictures of what you deem to be correct - as though the auditory system were automatically performing small scale micro translations on incoming data in order to compensate for 'deviant' forms, so's to assist you with your comprehension (and that this happens before you've even had a chance to start analysing).I think it is much more common to talk about the 100-metre* race (just like it was the 100-yard dash) in the past. I would punctuate them: 100-metre race (with a hyphen), 100 metres' race (with an apostrophe - but I still don't quite like this). If you leave out race, you could just say, 'He ran the hundred metres.'

What makes you think this? As most native speakers on this thread have said, the usual form of meter/metre is singular, just like any other attributive noun.The role is:
if (the) or (a) comes before the numbers, we don't put the (s), like: the 100 meter race... I run the 100 meter race. (because 100 is noun here not a count).
and if there is not (the) or (a) then we put the (s), like:100 meters race... I run 100 meters race. (here 100 is count of something).
