Alongside the North West 200 and the Ulster Grand Prix - both in Northern Ireland - the Isle of Man TT is one of the most famous motorcycle road races in the world.
Originating in 1907, the Isle of Man TT is a time-trial race held over two weeks - one week of practice and one week of racing - held on public roads across the Isle of Man.
While the speed and tight cornering has made it one of the most popular races for riders across the globe, it is also one of the most dangerous racing events in the world.
Billed as “38 Miles of Terror” by Franz Lidz in Sports Illustrated in 2003, the lack of forgiveness offered by the Manx roads means any small slip-up can end fatally.
Since its inception in 1907, there have been 258 recorded deaths of competitors in the Isle of Man TT.
But including bystanders and unreported fatalities, it is believe the total number of deaths surpasses 270.
In last years competition alone, three riders were killed, including 30-year-old Dan Kneen.
The deadliest year for the race period of the Isle of Man TT was 1970 as six people died during the event.
So why is the race so dangerous?
The 37.7-mile mountain course ranges from sea-level to 1,300ft and contains 264 corners - all on public roads - with riders regularly surpassing the 200mph mark.
Kawasaki rider James Hillier even registered over 206mph on the famous Sulby straight in a parade lap in 2015.
While the course hasn’t changed since the race began, the technology and speeds reached have dramatically increased, meaning the margin for error is now even smaller.
There are no catch fences, no runoff zones, no soft landings and roadside hazards - trees, buildings, old stone walls, even spectators - are just feet away.
Former Isle of Man TT winner, Richard Quayle, once told the New York Times: "If Roger Federer misses a shot, he loses a point. If I miss an apex, I lose my life."
