The climb starts at about 700 feet in altitude and raises another 3700 feet.
From parking lot to summit is 4 miles. For the down portion .. even though I shouldn't - I do a lot of running. It can be hard on the knees, but I keep the legs bent, never stiff. This way I'm using a new set of muscles for control and stability. If I feel like I'm being too rough I slow down and walk fast.
Heres a picture, climb starts on the right slope and ends near the point in the middle of the pic
