Sand marble racing

The 2017 Sand Marble circuit (marbles "racing" one another down a carefully-cut path in sand) is underway, and here's the Netherlands leg for your enjoyment.

In this tournament, a ghost marble will chase the competitors to push up marbles who got stuck on the course. The ghost marble does not count on the end results and will not be shown on the results list.

It's almost as good as puppy bowl, but I wonder if it would be even better with just the ASMR clacking of glass rather than the parodious commentary.
