Leave Blackalls Park PS travelling east on Todd Street. Cross South Parade to the Greenway-Cycleway and travel south-east to Stoney Creek.
Join Cook Street at Stoney Creek and travel south turning left into James Street at the tennis courts/bowling green.
Turn left onto Cary Street and travel north to Nelson Street. Turn left into Nelson then right into Oak Street.
Take a right at Day Street, carefully crossing the busy Cary Street and right turn into Renwick Street. Travel south past Toronto Public School and immediately turn right into Bay Street (passing McDonald's Toronto).
Cross Cary Street at the traffic lights in front of McDonald's and proceed a short way south adjacent to Cary Street.
Turn right onto the Greenway-Cycleway and head back through Blackalls Park in a generally north-westerly direction.
Continue on to the Fassifern Greenway-Cycleway intersection whereupon you could make a U-turn.
Head back south a few hundred metres and exit the Greenway at Rose Street. Travel west. Cross South Parade and immediately divert into Rupert Street. Travel (generally) south west about 200m and arrive at Blackalls Park Public School at the intersection of Todd Street.
A slow rider (such as me) can manage this rout in 26-33 minutes even on a 37C (100F) day such as today. DRINK PLENTY!
