There's not many long ones, but there are some short (500 meters) that will test your tuck and really gets you fast, there's one street not far from mingara McDonald's, it's Roberta st, on the other side which has Northumberland ave turn at the middle. From the top and pushing as hard as you can and tucking hard can get you around 65-70 kmph, it's where I usually practice my push and tuck. But you just really have to look around.
