Had an MRI on my knee after work (results still to come), and moved on from there to do a session at Fitzroy - supposedly ground-zero for the inner-city trendies. I missed the opportunity to help in plotting the global socialist revolution, perhaps through not fitting in sufficiently with the crowd - after all, I live in a suburb that doesn't have trams, eat meat, have been known to drink instant coffee and have never voted for the Greens.
(For those for whom this has gone as much over their head as the water at the end with the 'ACQUA PROFONDA' sign, enlightenment can be found
here.)
The session itself was reasonable, although I definitely notice the lower intensity compared with riding. Got the message (running to try to catch the green pedestrian light) that running is not a realistic option for the moment, despite some improvement in other respects.
