And my hint. If you’re going clockwise, as most do, don’t come straight off the boat and immediately turn left when you leave the terminal. Especially if it’s cold and you’ve been hanging about on the car deck for 15 mins.
If you do, you’re hitting the first hill with no warmup.
Do a few hundred yards to the right, then turn back, just to stretch your legs.
Dont ask me how I know this...
