The TT Mountain Course is 37.73 miles long, it includes more than 200 corners and requires more than 500 marshals for every practice and race session
From public road to race course
The world-famous course has been raced over for more than 100 years
It is an everyday public road which is closed to traffic, pedestrians and animals under the Road Races Act for two fortnight periods every year - two weeks during May/June for the TT and two weeks during August/September for the Classic TT and Manx Grand Prix - to allow motorcycle racing to take place.
Twelve Sectors
For marshalling purposes the course is split into 12 sectors, each with its own Chief Sector Marshal and numerous Deputy Sector Marshals. More than 500 marshals are required across the whole twelve sectors for every single practice or race session.
Chief Sector Marshals report to the Chief Marshal and the Clerk of the Course. They are responsible for the day-to-day manning of their sector, overseeing all equipment, managing a team of deputies and liaising regularly with Race Control.
The Deputy Sector Marshals oversee a specific area within the sector. They are responsible for welcoming new marshals, allocating jobs, organising appropriate cover at each marshalling point and overseeing any incidents within their area.
