THURSDAY, 1 MAY - REMEMBERING AYRTON SENNA
Here's a flavour of the tributes across the media on the 20th anniversary of Ayrton Senna's death.
Senna had everything it would take to create the grand prix hero of Hollywood's dreams. But something else, something more mysterious, captivated not just the fans who continue to revere his memory but later generations of drivers to whom he represents a permanent reference point.
Senna was an all thrills, many spills and naturally talented racer. But what about those who don't remember Senna, those that were either too young or perhaps not even born that now consider themselves part of the racing community? There are only so many YouTube videos and films you can watch, but it's never the same as seeing Senna live.
It was raining in Imola on Monday. Formula 1 stopped coming here eight years ago and moved on to lavish new circuits in Singapore and Abu Dhabi. There is blood on this track and time cannot wipe it away.
Ron Dennis, one of the people to have worked most closely with the triple world champion, found some of Senna's weaknesses to be the source of amusement, reminiscing that a driver who strapped himself so tightly into the car before winning in Brazil for the first time struggled with any pain outside of the cockpit.
Twenty years later, there is still no threat to Senna's status. Schumacher, Fangio, Prost and Sebastian Vettel have garnered more titles, but Senna is heralded as the greatest by every contemporary and every young pretender who has come since. They marvel at the dexterity of one who could propel himself from fifth to first inside 40 seconds in the wet, at the audacity of one who shunted Prost into the Suzuka dirt without so much as a trace of contrition.
Players of Brazilian football club Corinthians paid a touching tribute to Senna by each donning a crash helmet as they lined up before their match against Paulista. The helmets were the same bright yellow and green worn by Senna.
The deaths of Aytron Senna and Roland Ratzenberger at the San Marino GP 20 years ago sparked a drive for F1 safety that continues to this day.
McLaren on Twitter: On this day in 1988 Ayrton Senna won for McLaren at Imola. On this day in 2014, we remember Senna.
Mercedes AMG F1 on Twitter: Two decades ago today the racing community - and the world - lost one of its brightest talents: the great Ayrton Senna. Remember Ayrton now as he shone brightest in life: dancing on the limit.
Lotus F1 Team on Twitter: We'll never forget the gift that you had and the gift that you gave to us.
Ayrton Senna would have ended his Formula 1 career at Ferrari had he not died at Imola 20 years ago, president Luca di Montezemolo says.
WEDNESDAY, 30 APRIL
Ferrari's Fernando Alonso and Kimi Raikkonen are to attend a memorial service at Imola on Thursday to mark the 20th anniversary of Ayrton Senna's death. The Brazilian, world champion three times, died from injuries sustained in a crash during the San Marino Grand Prix on 1 May 1994 aged 34.
Three-time world champion Sir Jackie Stewart said Senna told him he would never again speak to the Scot who accused him of deliberately crashing into Prost to win the 1990 title.
McLaren chief executive officer Ron Dennis says he won a $10,000 (£6,000) bet with Senna that he could not eat a container of chilli in Mexico. "That was about the fourth time he had lost a bet, a big one," said Dennis.
