Hmm well the Clypse course was only in use for a few years during the 1950's, BUT, when the Mountain course was first used around 1911 they turned off at Cronk Ny Mona and Arrived at St Ninians crossroads at the top of Bray Hill via Ballanard Road so it could be that stretch of road was used during those years but in reverse direction to the Clypse course.

Edit- This info found on the net confirms the above, but the route was only used from 1911 to 1914, after which the current layout was used.


The original Mountain Course measured 37 1/2 miles, the difference being that riders turned right at Cronk-ny-Mona, down Johnny Watterson's Lane, to Ballanard Road, turned left again along Ballanard Road to St Ninian’s, where they turned right down Bray Hill.

The start was on Quarterbridge Road, with refuelling depots at Braddan and Ramsey.
