I'm struggling to get much over 170-175 at threshold/maximum these days.

I had to have a holter monitor (portable ECG piece of apparatus) fitted a few months back as they found an abnormality in my heart rhythm. They thought it was something called a prolonged QT interval which can be related to long QT syndrome which can lead to sudden death. So that was a fun six months waiting for the NHS to get their shit together for the results - which turned out to be normal. But the cardiologist did comment on the efficiency of my heart, due to doing lots of running and cycling.

So sack the walking off Lulu, and do some proper exercise.
