text: The origin of Basque Trials of Strength is found in the daily tasks carried out across the region. For centuries, young Basque farmers pitted themselves against each other in physical challenges. Labouring in the forests of the Basque country gave rise to the challenge known as aizkolariak (based on lumberjacks working with an ax or arpanariak), as well as athletic sawing of tree stumps and wood. The construction of buildings, often based on large stones for the cathedrals and monasteries led to the development of the challenge known as arrijasotzaileak – literally those who lift stones.
  Several events originate from working in the fields, the best known of which is lastoaltxatzea, the lifting of straw bales. This is done either using a pitchfork or a pulley, and is often organized in tandem with joko (cart-lifting), zakulasterka (individual relay or sack races), and untziketariak, a race involving pitchers of milk. Also well-known is soka-shot, or tug-of-war, which is an internationally recognised discipline celebrated in fourteen countries. During the summer, demonstrations of Force Basque are organised by the local Xiste organization, often at the main municipal arena in Saint-Jean-de-Luz.
