Some notes on the route:

East Gippsland Rail Trail : 100 Kilometres of natural diversity running from Bairnsdale to Orbost.

The Quinnipiac & Regicides Trails form a "Y", meeting near the summit of High Rock in Hamden, CT.  This route runs both twice, so you can start anywhere.  About 50 miles total.
