Gradual and straight into a 50 k/h SE it took almost 3 hours to get to the Lake Argyle turnoff after 35k where I had a long lunch break. I had previously decided against the 70k detour to the lake - people recommended it (probably because it's one of the few lakes in Australia) but to me a lake is a lake and 70k on a heavy bike and hilly road is far just to take a look and go back...
