This annual fun run is underway as I key in this post. The run is from the Central Business District to Bondi Beach; something like 14 kilometres from memory. The elite athletes complete the course in about 45 minutes but others run or walk the course (which includes some horrendous hills) over a period of 2/3 hours.
This year the field is expected to be about 80,000.
Early runners in the field passing through Edgecliff, where I live;
The same runners (possibly) moments later passing through Double Bay to my east:
