Ian Hutchinson crashes in the Isle of Man TT 2017 Senior Race
This is how Ian Hutchinson's Senior TT came to an end last year. A big crash up on the mountain which left him with a shattered femur and a busted ankle.
After a year of rehab and rebuilding he's back on the grid today on a Honda.
TT paddock comes alive
BBC Sport's Richard Petrie at the Isle of Man TT: "This is the biggest of the year in the international road racing calendar and tens of thousands of fans have been booking their favourite vantage points behind the hedges, stone walls, fences and gardens around the 37.73-mile course since early this morning.
"There is a special buzz about Senior TT day - a palpable sense of anticipation ahead of the blue riband event of the meeting and many of the island's population swell the number of spectators as today has been designated a public holiday on the Isle of Man.
"In the race paddock, mechanics have been meticulously making last-minute checks on the machines in a sport where attention to detail is not only critical to performance and result, but also to the riders' very existence."
Image source, iomtt.com"The area behind the Grandstand is heavily populated with fast food stalls, ice cream vans, merchandise sellers and traders in bike accessories, while corporate hospitality has become a feature of the more professional era of the TT over the last decade or so.
"A carnival atmosphere prevails as, unlike the more closeted world of MotoGP, the fans can mingle freely with their road racing heroes, collecting autographs, taking photos and getting up close and personal with the flying machines which will soon take to the grid for this most sensational of motorsport spectacles."
Tyco BMW
Michael Dunlop has won the Senior TT on three occasions, including last year. Last year he beat Peter Hickman, with Dean Harrison third.
Could it be the same top three again?

Image source, iomtt.comBBC Sport's Richard Petrie at the Isle of Man TT: "The Isle of Man TT has often been described as the 'last genuine white knuckle ride in motorsport'. It's an event which evokes every conceivable range of emotions - where triumph and tragedy are all too often regular bedfellows.
"This TT fortnight has been no exception - we have marvelled at the incredible exhilirating high speed record-breaking exploits of the finest exponents of road racing in the world - enjoyed the intoxicating mix of the roar of engines, the smell of the oil, the flash of colour as man and machine hurtle past just feet away on public roads at breathtaking mindblowing speed, almost like guided missiles. The ultimate challenge of man and machine.
"We have also experienced the gut-wrenching lows as Manx rider Dan Kneen and Scottish newcomer to the circuit Adam Lyon paid the ultimate price on this most unforgiving of circuits. Their deaths the latest in a long line of tragic reminders of the inherent risk and danger of racing on the Isle of Man Mountain Course."
We are half an hour away from the start of the race...

Prince William starts Isle of Man TT race
Image source, iomtt.comThere's every chance that we could see a 135mph lap today. To clarify, that's an AVERAGE speed of 135mph over the full 37.7 mile lap. Which would be absolutely insane.
It doesn't feel five minutes since the riders were hoping for a 130 lap which is now basically routine.
Dean Harrison set a new outright lap record in the Superbike race of 134.432mph on his Kawasaki. Could that go?
The big race, the last of the week, the Senior TT is away at 12:45 BST but the sidecar race has just finished.
It was won by the record breaking Birchall brothers once again, Ben and Tom. That's eight wins in a row on the sidecars.

Lap records all the way
BBC Sport's Richard Petrie at the Isle of Man TT: "It's been lap records and personal best speeds all the way this week as the riders have made the most of the perfect conditions which have been a constant feature of this year's event.
"With the sun shining, plenty of rubber down on the track and course conditions ideal, everything is conducive to more high speed exploits in today's grand finale, with Michael Dunlop, Dean Harrison and Peter Hickman well fancied to carry their outstanding form into this race.
"The Senior TT is not only the culmination of a fortnight of practice and racing on the Mountain Course, but also of a festival of motorbike related gatherings, events, displays, exhibitions and concerts off it."
If you're not familiar with the TT and how it works, you're mising out on one of the greatest sporting spectacles on the planet.
Racers hurl down 'normal' roads, setting off every 10 seconds in what is essentially a time trial. They race the clock as well as each other.
All set?
Head down, flag up, throttle open.
The riders racing in today's Senior TT will hit 85mph in first gear, will be doing 160mph in just a handful of seconds before they plummet down Bray Hill.
Image source, iomtt.comThey face six laps of the world famous 37.7 mile Isle of Man mountain course, a supreme test of skill, bravery, concentration and mechanical integrity.
At the end of it all one man will lift the Marquis de Mouzilly St. Mars trophy and put his name into the record books for all time.
Image source, iomtt.comWill we see a barely believable 135mph lap? The 50th win for the Dunlop family? A shock result?
So many questions, we will find the answers soon enough. Welcome to the Senior TT...
