Some race-day problems do not show up until the first hard turn.
A line of competitors runs toward a grassy football field and funnels through a muddy corner.
The filmer, Alonso, told WooGlobe: "During the Spanish Club Duathlon Championship in La Nucía 2026, it was raining all morning, and on a turn on the football field grass there was a lot of mud, causing everyone to slip as they passed."
One after another, shoes lose traction and bodies slide sideways, with several athletes stumbling and dropping to the ground before getting back up and moving on.
The same patch of ground keeps resetting the race into a brief test of balance.
The moment passes quickly, leaving a trail of near-identical slips in the same spot.
