(early thoughts)
1. ATHLETICS - Men's Pole Vault - Władysław Kozakiewicz Gold in Moscow 1980. Gold in Moscow 1980. On July 30st, 1980! In Moscow! And you know the gesture he showed to the audience.... July 30th ... And you know what happened in August 1980 here :-) Solidarity movement, Lech Wałęsa... Kozakiewicz will be always part of this story.
2. VOLLEYBALL - Men's Tournament - Gold Medal in Montreal 1976, beating USSR 3-2 in a final. In 1976!!!
3. ATHLETICS - Men's 10,000m - Janusz Kusociński winning gold in LA 1932. He was killed by Germans in mass execution in 1940.
4. ATHLETICS - Women's 400m - Irena Szewińska gold in 1976. WR. Probably the best Polish athlete in history, many say.
5. SKI JUMPING - Men's NH and LH - 2002, Adam Małysz in SLC, this was THE BIGGEST HYPE here you can possibly imagine. No gold though.
