It seems the TV is taking his time to upload today's competition to internet. Let me giving you a little bit background information meanwhile.
Basque sports are also known as Basque rural sports or simply rural sports. The reason of this is that all the types of Basque sports (except "Pilota" or "Jai Alai as its known in some places of America) come from or are derivatives of rural or seamen jobs. You can find axeman competitions, scyte competitions, running with a weight in your back, rowing, anvil lifting, bale trowing, chariot moving, stone drilling... All were professions, jobs, or tasks someone performed everyday.
All is changing nowadays so I will speak in past, it doesn't mean we are not like I'm going to explain now, but our personallity is more or less diluting nowadays. Basque were proud people, so when somebody said he was better than any other in any task, the other directly challenged the first. Add to it any verbal promise made by a Basque was like a handwritten documment with a notarial seal and you have the perfect ingredients for a higly competing society.
You are seeing one of those sports in the breaks of the Egursport, that's the harrijasotzea (stonelifting). Here you have a documentary subtitled in English about it, enjoy it!
