Lee Johnston won his first career TT, taking the first of two Supersport TT events at the 2019 Isle of Man TT. Johnston won the race, shortened from four laps to two due to rain, averaging a speed of 126.449 mph on the Mountain Course.
James Hillier held the lead early in the race, but Johnston took over the lead near the end of the first lap. As the skies opened up on the second lap, race organizers made the call to reduce the race length.
Johnston led Hillier by 3.9 seconds after passing through Glen Helen on his second lap, with Peter Hickman an additional half a second behind. Hillier then started gaining on Johnston, cutting the lead to within a second. If the race had continued on its scheduled length, Hillier may have regained the lead had he kept that momentum. Instead, it was Johnston earning his first TT win, with Hickman in third, all three podium finishers with average speeds topping 126 mph. James Hillier led early and came on strong late but was unable to beat Lee Johnston.
Peter Hickman finished third for his second podium of the day following his win in the Superbike TT.
