many british athletes improve 5 secs between 14 and 16

whos the athlete? or you talking generally? pardon my ignorance

have a look on the mccain british rankings, no one in particular just ordinary schoolkids the improvement in some is phenomenal, nothing untowards just growth etc, my son is 13 and over last 2 years was stuck on around 13.8 for 100, 1st run this year 12.4 without training etc ,so there is drastic improvemrnt in the 13/ 17 years imo.

ps i also tell you those with their birthdays say feb to august more improvement in them as they get to 15/17.

just checked the chinease girl, of course youll get massive imp, born in march

Those Jan Mares....quality stock

early foal

sept mares in athletics, seriously though around 80% of top uk junior athletes are born sept/ oct, around 16/18 they then come to a level playing field. i was a august born , if mum had waited another 2 weeks id have been a sport superstar in my year.

I suspect the improvement decreases the closer you get to the world record. That's the bit people are ignoring when they say 5 sec improvement is normal for a 16-year-old. Also she swam the last length faster than the best man. It's quite right people are sceptical and that's the legacy of all the cheating bastards who are allowed back in the Olympics after a couple of years following their abuse of the system. Many like Vinokourov don't even give a damn.
