Which runners have won an Olympic medal 12 years after the first medal?

Gatlin - won 100m in 2004; likely to medal in 2016

The weirdest 12-span is by Fernando Mamede:

1972: Ran anchor leg for Portuguese 4 X 400 meter relay team (7th in the final).

1984: DNF early in the 10,000 meters from anxiety despite being the world record holder.

Derartu Tulu

Merlene Ottey

Veronica Campbell-Brown

Jackie Joyner Kersee in the Heptathlon and LJ

Carl Lewis in the LJ

The LJ is not a running event. So strike Kersee and Lewis. Can you provide the data for the other three? Or is that my responsibility?

Use trackbot

Yes, it is your responsibility. Nevertheless, here is Tulu's information, to encourage you:

Derartu Tulu

1992 10k gold

1996 10k 4th

2000 10k gold

2004 10k bronze

I'll do your work for you.

Derartu Tulu won gold in the 10,000 meters in 1992. She won bronze in the 10,000 meters in 2004.

Merlene Ottey won bronze in the 100 meters in 1980. Bronze in the 100 and 200 in 1984. Nothing in 1988. Bronze in the 200 meters in 1992. Silver in the 200 meters in 1996. Silver in the 4x100m relay in 2000.

Veronica Campbell-Brown won silver in the 4x100 meter relay in 2000. She won bronze in the 100 meters and gold in the 200 meters and 4x100 meter relay in 2004. In 2008, she won gold in the 200 meters. In 2012, she was 3rd in the 100 meters, 4th in the 200 meters, and second in the 4x100.

The question wasn't addressed to you. But since you answered the question, it's your responsibility to explain why it's my responsibility. So tell me, if someone is asserting a name, why is it not their responsibility to provide the data for that name?

Why don't you use trackbot?

Grete Waitz:

1972: 1500m eliminated in heats

1976: 1500m eliminated in semis

1980: Norwegian boykott

And Maria Mutola from 1988 until 2008 over 800m

Fanny Blankers-Koen competed in 1936 in the relay and in 1952 over 100m and the hurdles

But another athlete who really matches the criterion of the OP is Irena Szewinska with relay Gold and 200m silver in 1964 and 400m Gold in 1976. She competed also in 68, 72 and 80.

Lots of people have run in 4 Olympics or more. Merlene Ottey ran in 7.

Barring disaster Felix will do it. Silver in 2004 in the 200.

Also, Angelo Taylor has not been mentioned. A gold in the 400m hurdles in 2000 and a gold in the 4x400m in 2012.

Lagat is going for 16 years. He won bronze in 2000.

Won't Lagat be 16 years?
