I managed to get in a little over 300 kms yesterday, but they were cold ones. It was sunny and dry though. We went south from New Glasgow to Sheet Harbour, then east to Sherbrooke, and then north to New Glasgow through Blue Mountain.
That probably doesn't mean squat to most of you, but if you're ever in NS and looking to spend ~4 hours on a nice day, that is a nice route. Just remember to top up in the towns.
