Overnight rains pushed the start time for the Supersport TT back by more than two hours, and riders were still cautioned about a couple of wet spots remaining on the Mountain Course. Once things got underway, it was James Hillier that took the early lead ahead of William Dunlop and his brother Michael. Other front-runners included Gary Johnson, Dean Harrison, Peter Hickman and Superbike TT winner Ian Hutchinson.
