Volunteers praised after week of disruption
The clerk of the TT course has paid tribute to the marshals, following a week of delays and cancellations.
The volunteers are needed in order for practice and racing to go ahead.
An extra practice session has been added this afternoon after four days of postponements due to rain, fog and mist.
Gary Thompson says the marshals are an essential part of the event:
