TT 2017 practice has been curtailed after one lap as mist descended on the Mountain and rider Dave Sellers crashed unhurt at the Gooseneck.

Riders were allowed out on a second lap but escorted by travelling marshals from Ramsey as visibiity was down to 100 metres at Brandywell and due to the conditions, the air-med helicopter cannot fly.

From a standing start, Ian Hutchinson was fastest on the Superbike, setting a 128.987mph lap, followed closely by Michael Dunlop on a 127.228. Dean Harrison ended in third with a 126.157 while Dan Kneen, who said he was crusing over the Mountain on his Superstocker, put in a 125.188 for fourth. Peter Hickman - also Superstock-mounted - finished in fifth with a 124.900, Conor Cummins sixth with a 124.738 and James Hillier took seventh on a 124.519.

Bruce Anstey took the RC213V-S to eighth with a 124.1240, just ahead of Gary Johnson’s 124.107 while Steve Mercer completed the top ten with a 123.984. Michael Rutter was 11th ahead of Martin Jessopp in 12th.

David Johnson put in a 123.607 in 13th to head North team-mate Josh Brookes who put in a 122.583 for 15th with Ivan Lintin in the sandwich on a 123.396. Guy Martin was 18th on a 121.416.
