His personal best of 5.71 metres was achieved at the
World Junior Championships in
Beijing on August 19, 2006, when he beat the old championship record (CR) of
István Bagyula from 1988, and the Argentine senior record. He also holds the South American indoors record, with 5.52 metres, and is the only Argentine athlete to conquer a gold medal in any World Championship at any category. Germán was first coached by his father within a family of pole vaulters; his brother
Guillermo Jr. (in 2001) and sister
Valeria (in 2005) also participated in World Junior Championships. During the
2006 South American Games, he won the gold medal (5.65 m) and his brother Guillermo silver (5.20 m). He currently trains in Italy with pole vaulting star
Yelena Isinbayeva, co-coached by
Vitaly Petrov. In 2010 Germán won the Platinum
Konex Award from Argentina as the best Athlete from the last decade in his country. In 2015, he finally broke his own national record (after 9 years), jumping 5.75 at the Pan-American Games. ==Personal best==
