mate, i think youre doing great guns to knock off black mountain like that. its a tough climb. i think ainslies last ramp is a touch steeper than anything else close to town? and red hill is pretty tough all the way, and great fun descending. stromlo, as mentioned earlier, is not as steep as the others ad isnt really all that long either. there are so many fun hills to ride around the can, and theyre so close to town that you can access them and measure your progress so easily. let us know your next milestone!!
