I see that Greg Hancock has retired from Speedway racing.  4x world FIM champion and 8X American AMA champion, in addition to other wins.

Hancock, 49, won his most recent Fédération Internationale de Motocyclisme Speedway World Championship in 2016. His other FIM Speedway titles came in 2014, 2011 and 1997. In the United States, he won eight AMA Speedway National Championships. Hancock also won FIM Team and Pairs World Championships, as well as many European domestic league titles during his career.

 

I understand his wife had some health problems and at his age, it's hard to compete with the crazy young guys.  But he had an amazing way of getting first off the line. 

 

I would root for Antonio Lindbäck if he was riding.

I use to like watching speedway at Wembley Stadium UK every Thursday.

They stopped venues there for some reason. 

papa loves watching speedway racing

online.

Hope to catch an 'in-person' event one day.

Here are some good Speedway GP heats from 2019: 

 

 

Hancock managed 4 world championships, despite some extremely stiff competition from champions like Hans Nielsen, Tony Rickardsson and Nicki Pedersen and Jason Crump:  https://en.wikipedia.org/wiki/List_of_Individual_Speedway_World_Championship_medalists
