Formula 1 arrives at the Emilia Romagna Grand Prix with a look to the past — it’s 30 years since Ayrton Senna’s death — and the future prospect of tougher competition for Max Verstappen and Red Bull.

Drivers joined a memorial run around the Imola track on Thursday evening to mark the anniversary of three-time champion Senna’s death in a crash there during the 1994 race.

Senna was a childhood hero to many, including seven-time champion Lewis Hamilton, who was nine in 1994, and is a part of F1 history for the 13 current drivers who were not born when he was killed.

Drivers wore shirts in Senna’s helmet colors of yellow with blue and green stripes as they gathered around a memorial at the Tamburello corner where he died.

The Brazilian and Austrian flags were laid out in memory of Senna and Roland Ratzenberger, who was killed in a crash in qualifying one day earlier.
