Good on you @Afraser. I find walking very boring so the street circuit is not for me at all. My arthritis means I have not been able to walk more than a house block for many years. Since January I have been using an exercise bike to strengthen the muscles around my knees and can now walk 3 kms in 40 minutes or less. Ballarat has a big lake (Lake Wendouree) and I have now walked the 6+ kms but in 2 stages (stopping for a cuppa at the 3.6 km mark). Not sure I will be repeating that too soon as people just refused to social-distance.
I agree, a small walking group would be helpful as long as they are not too fit. Company is a good motivator.
