Competing on three wheels for first time
Competitors are making their way to the TT - ahead of Saturday's first practice session - and some are already here.
There's activity in the paddock, with plenty more due in the coming days, as more riders and their teams arrive.
Some have come straight from the North West 200, like Maria Costello.
She'll be competing on both two and three wheels this TT, and is delighted to be here once again:
