Hi Albert,
I have to confess I did once try to venture up Telstra towers (Black mountain), only to give up after about 3 mins of pedalling as I saw my heart rate rocket up to 170bpm. Also I couldnt (didnt) get up this morning to tackle the mountain.
I did do Mt Stromlo a while back, and thought that the gradient was pretty suitable for steady climbing. Pity its a bit too far for a morning training ride as it would take me too long to get there, climb, and then get back home in time to get to work.
According to the C2M website, the avg gradient of Black Mountain and Mt Ainslie is 8% while that of Stromlo is 4%. The top guy flew up stromlo at avg 32km/h. I remembered struggling to maintain 15km/h. But I have had done more kms since then, perhaps I could be ready for black mountain.
My motivation for this training is so that I dont get dropped by the group each time the road turns upwards. I have read that the formula for climbing is the power to weight ratio. To increase power, should I be consciously trying to stomp rather than trying to spin? (not that I can spin at the moment).
