Good job, jmd. It is Juan Carlos Zabala who was born today some 101 years ago. Zabala was only 20 at the time he won the 1932 Olympic marathon in Los Angeles. He was named as Argentina's track and field athlete of the 20th Century.
Good luck with Bucolic and remember, no looking it up or using any resources. The idea is to use only your brain. I can give more clues, if you need.
I've taken the hint that one ran with something in his hand as a relay medalist. Figuring the age of the younger one, it would be either the 60, 64, or 68 Olympics. I read the Rome book, and I think that Germany won the men's 4x1, so that is a possibility. I think that the US swept the men's relay medals in 64 and 68. If it is Germany's 4x1, I have no idea who ran on it other than Hary. The BC initials doesn't help me much.
It could be a woman, though I doubt it. Notwithstanding, the quote "in his hand." I'm not sure that women had 4x4 in those years, and I'm pretty sure that the US won the 4x1 in 60. Not as sure about 64 and 68.
LopenUupunut, you got him. Yesterday was Bernd Cullmann's 73rd birthday. If you are not familiar with Bernd Cullmann, it might be because you also don't know Walter Mahlendorf. Bernd and Walter ran the first and third legs on the winning four by one relay in 1960's Rome Olympic Games.
You probably know the second and fourth legs: Armin Hary and Martin Lauer.
The U.S. team crossed the finish line in first place, but was later disqualified. Germany tied the world record of 39.5.
