Victory in the 2010 Senior TT has given Ian Hutchinson the record of becoming the first man in the event's 103-year history to win five races in a week.
The Padgetts Honda star had already secured victory in the Superbike, Superstock and both Supersport races.
All eyes were on the Yorkshireman as the race got under way, but he faced strong competition from the likes of John McGuiness and Keith Amor, both riding for HM Plant Honda, Guy Martin on the Wilson Craig Honda and flying Manxman Conor Cummins on the McAdoo Kawasaki.
The six-lap race was marred on lap three when Martin, who was leading at the end of lap two, crashed heavily at Ballagarey. His bike caught fire and the race had to be red flagged while fire engines attended. Martin was air-lifted to hospital with chest injuries.
The Senior TT was re-started, with a reduced distance of four laps. But the re-run was also hit by a serious accident when Cummins crashed on the second circuit at the Verandah. He was taken to hospital with arm and leg injuries and his condition was described as 'serious but stable'.
In the initial race Hutchinson, McGuinness, Cummins and Martin went head to head over the first two laps, with all four lapping at over 130mph and less than six seconds splitting the quartet after the first pit stop.
When the race re-started at 3pm, Hutchinson stole the early initiative, but it was close and his advantage over McGuinness at Glen Helen was just half a second. Cummins was only a tenth further back in third with Donald in fourth and Michael Dunlop and Ryan Farquhar in fifth and sixth - just three seconds splitting the top six.
By Ramsey Hairpin, Hutchinson had edged 1.14s clear and McGuinness held a similar advantage over Cummins, the gap between those two 1.5 seconds. As the riders flashed across Glencrutchery Road for the first time, Hutchinson led with an opening lap of 131.487mph but it was close with McGuinness only 0.61s adrift, the 15-times winner having clawed back some time over the Mountain. Cummins was still in contention, only two seconds behind in third whilst Keith Amor was now up in to fourth closely followed by Farquhar and Anstey, both of whom had retired from the earlier abandoned race.
Hutchinson eked out a further two seconds on the second run to Glen Helen but no sooner had he passed the timing beam than McGuinness was out, the HM Plant Honda having coasted to a halt just on the exit of the left hander. This promoted Cummins up to second but he found himself 3 seconds behind as they reached Ramsey. Amor, Farquhar and Anstey were all promoted up the order with Ian Lougher now in sixth but there was further drama when Cummins had failed to reach the Bungalow.
Cummins' crash allowed Hutchinson's lead to rocket up to 27 seconds, another 131mph+ lap helping him on his way. Amor was close to his first ever 130mph lap in second with Farquhar, Anstey, Lougher and Michael Rutter now occupying the leading six positions.
