The 25-mile TT starts on the north side of Connel Bridge. Parking and registration normally happens here, though recent construction works means that car parking will be in North Connel or anywhere nearby (will update the construction status when possible).
The route is an out and back heading northbound on the A828 towards Loch Creran. At the roundabout before the bridge, take the first exit and go around the loch until you reach the 5th telephone pole after the Glasdrum car park. Here you will turn around and return the way you came, finishing the start location.
