The Isle of Man TT Mountain Course or TT Course or Snaefell Mountain Course or Elmo’s Mountain Course[1] is a street and public rural road circuit located in the Isle of Man, used for motorcycle racing. The motorcycle TT Course is used principally for the Isle of Man TT Races and also the separate event of the Isle of Man Festival of Motorcycling for the Manx Grand Prix and Classic TT Races held in September of each year.[2] The start-line for the Isle of Man TT Mountain Course is located on Glencrutchery Road in the City of Douglas, Isle of Man.[3]

The clockwise course has a lap of 37.730 mi (60.721 km),[4] from the start line at the TT Grandstand on Glencrutchery Road (A2 Ramsey to Douglas) in the island's main town of Douglas.[3] After negotiating urban streets, the racing circuit turns right to leave Douglas at Quarter Bridge, then proceeds along the A1 Douglas to Peel Road from Braddan Bridge, through the villages of Union Mills, Glen Vine, Crosby, and Greeba. The course then turns right at Ballacraine on to the A3 Castletown to Ramsey road, firstly through countryside glens followed by agricultural land interspersed by the villages of Kirk Michael, Ballaugh and Sulby, finally intersecting with the A18 Snaefell mountain road after negotiating urban streets in the town of Ramsey. The A18 then takes the course back to Douglas through the highest point, situated after the Bungalow at Hailwood's Height near the 31st Milestone and the UK Ordnance Survey spot height of 1,385 ft (422 m) above sea level. The descent starts through countryside before entering the residential outskirts of Douglas back to the finish line.
