Rainer Schmidt started as a winner of the 1966 Youth Spartiakiad. But due to a broken collarbone he had to skip further junior’s events. In 1968 he joined the national team of the GDR. After the death of his first coach Hans Renner he missed many good results due to a poor landing. In 1971 he was national champion and won the Tatra Cup. He won the Four Hills Tournament 1972/3 and a season before the bronze medal at the Sapporo Winter Games from the large hill, placing 15th from the normal hill. In Sapporo he failed to achieve an even better result due to the changing winds. At the FIS Ski Flying World Championships 1975 he earned another silver medal. He later studied at the DHfK sport university in Leipzig and made his living as a youth coach at Oberhof.
