relais

Relay comes from Old French relais, from relaier, meaning 'to leave behind' or 'to release fresh hounds.' In medieval hunting, relay stations positioned along a chase route held fresh dogs that were released as the lead pack tired. The word named the replacement, not the race. A relais was a reserve — something held back until needed.

The postal relay system adapted the concept. From the Persian chapar khaneh to the Mongol yam to the American Pony Express (1860-1861), relay stations allowed riders to switch horses and continue at speed. The word expanded from hunting dogs to horses to any system of sequential replacements. Benjamin Franklin organized the first systematic postal relays in the American colonies in the 1750s.

The athletic relay race appeared in the late nineteenth century. The first known relay race was held in the United States at the Penn Relays in 1895, though fire brigades had organized relay-style bucket-passing competitions earlier. The 4x100-meter relay entered the Olympics in 1912. The baton — a hollow tube passed between runners — formalized the handoff that hunting dogs and postal horses had performed instinctively.

The dropped baton has become one of sport's most dramatic failures. The 2008 United States men's and women's 4x100 teams both dropped the baton at the Beijing Olympics. Years of training erased by a fumbled handoff lasting a fraction of a second. The word relay still carries its original meaning: the moment of transfer, when what was carrying the effort changes hands.
