Check out the different run circuits around my home and who inspired them, I think Brett has been influenced by all of them to a degree
The one above is the sand track, from another Aussie coach from the 50′s and 60′s Percy Cerutty . Not quite the sandhills of Portsea but about as close as you get around Cambridge.
Above is my home grass track, I try not to run on it to much and go to Hamilton to the Tartan track as “Grass is for cows” But the triple gold medalist from Czech Emil Zatopek did alot of laps around his track and so do I some weeks.
This is the Horse track circuit from Ron Hill, Aussie runner to go under 2hr10min for the marathon. Round and round, faster and faster
And finally the Brett Sutton Leysin Hill circuit but in Cambridge, New Zealand. About 5min around with a nice little climb
