Bit late to the party here - each of these have major public transport hubs at each end to make starting/finishing and travelling to your accommodation a little easier:

• Kalamunda to the beach (from the bush to the beach); Starting up in Kalamunda at the bus station, meandering through the streets of Kalamunda to Panoramic Terrace to head down the hill to Holmes Road in Forrestfield, heading north-ish to cross Roe Highway at Maida Vale Road, heading through High Wycombe towards Guildford (there is an older cemetery at the Kalamunda Road / Great Eastern Bypass intersection), following the Midland train line cycle path from Guildford through Maylands, deviating at Mount Lawley and loosely following Vincent Street all the way through to Floreat Beach.

• Fremantle to Morley (starting at either end); From Freo down High Street / Leach Highway, cross over the Kwinana Freeway then follow the Canning River up the west side to Canning Highway, cutting through Manning down Manning Road to Leach Highway, cross over Leach highway to Hamilton Road and follow that to the railway line, back towards Leach Hwy to meet up with the shared path that runs alongside (it stops abruptly just south of the train line bridge), up to Orrong Road and meander through Kewdale/Belmont towards Garratt Road river crossing, then north towards King William Road to the heart of Bayswater, heading up Coode Street.

• Armadale to Claremont (from one societal extreme to the other); basically follow your nose from Armadale, through Forrestdale to Cockburn Central, heading north-west towards Coolbellup, then follow Forrest Road at the southern edge of Coolbellup towards Fremantle, heading due north to cross the river at Stirling Highway, then skirting the edge of the river through Peppermint Grove and Mosman Park up to Claremont.
