Hickman fastest in Superbike class during fourth qualifying session

It was Peter Hickman who was quickest in the Superbike class during last night's TT qualifying session, with a 133.797mph lap, with Michael Dunlop less than a second behind. 

Later on, Ben and Tom Birchall not only set the best qualifying lap ever in the Sidecar class, but also dipped inside their own lap record with a speed of 119.414mph. 

In other news, Maria Costello has been withdrawn from racing in this year's TT.

Organisers confirmed the decision was taken following instruction from the Chief Medical Officer - no further details have been provided. 

Looking ahead, today's qualifying session will take place this afternoon, with roads beginning to close from this morning.

The Mountain will close from Ramsey at 11:15am and from the Bungalow at 11:30 - the rest of the course will shut at 12:30pm.

Sidecars will then set off at 1pm, followed by the Supersport and Supertwin qualifying at 1:45pm, and the Superbike and Superstock at 2:45pm. 

Roads are expected to re-open no later than 4:30pm. 

Meanwhile, Bushy's TT Village is open from midday until midnight at the Villa Marina Gardens, and Ramsey Sprintfest gets underway from 7pm in Market Place.
