Galfione won six successive French National Athletics Championships outdoor pole vault titles at the senior level from 1993 to 1998.

He also won three French National Athletics Championships indoor pole vault titles at the senior level in 1990, 1993 and 1994.

All of them subsequently had three consecutive misses in attempting to clear heights greater than 5.92 m, and the contest was therefore declared over.

At first, Galfione's clearance at that height was ruled invalid because it appeared that he had illegally touched the bar with his hand.

But after the French team lodged an appeal, the decision to rule Galfione's 6.00 m clearance invalid was reversed, and he was declared the winner of the competition.

He also became only the fourth pole vaulter, after Sergey Bubka, Rodion Gataullin and Maksim Tarasov, to clear 6 metres or more indoors.

[2][6][9][10][11] Galfione also worked as an athletics commentator and consultant for Canal Plus and presented documentaries for the French television channel, Voyage.

[12][13] Jean Galfione has one brother (Olivier, who is an actor) and one sister (Sophie, who is a model), and is a nephew of an Olympic medal-winning fencer, Jean-Claude Magnan.
