Well chuffed with myself.... I can officially confirm that completing W5R3 is more "mind" over "muscle". I took a nice slow pace (avg 9min/km) and just kept plodding. When finished, I did the warm down walk and took another little run back home.
Yes, the plan works... still recall the struggle during the early weeks.
Ever onward... W6R1 on Monday if weather permits!!
Slow_Rob - Look forward to hearing how you get on with yours and anyone else about to tackle this one.
