The Blue Riband event of the Isle of Man Centenary TT Race week was the Senior TT race over 6 lap (226.38 miles) of the TT Course. The first lap quickly produced retirements for three of the race favourites with Ryan Farquhar retiring at the Hawthorn near to Greeba Bridge, Martin Finnegan at Ballig and the winner of the 2007 Superstock TT Race when Bruce Anstey retired at the TT Grandstand at the end of lap 1 with handling problems. Despite cement dust on the road at Guthrie's Memorial and at Sarah's Cottage and also some low cloud on the higher sections of the Mountain Section of the course, John McGuinness completed lap 1 in a time of 17 minutes 25.77 seconds at an average speed of 129.883 mph of the 2007 Isle of Man Senior TT race and led Guy Martin in 2nd place, also riding a Honda by 10 seconds and in 3rd place Ian Hutchinson with an average speed of 128.414 mph. Although the time for lap 1 of the Senior TT was only 4.5 seconds short of an average speed of 130 mph, John McGuinness completed the second lap at a faster pace and lapped in 17 minutes, 21.99 seconds at an average speed of 130.354 mph to finally break the 130 mph speed barrier setting a new class and TT Course outright lap record.
