I am glad you wrote "vertically" there. I'd be a bit worried if you were proud of covering 650' of distance in 12 minutes. :)
There will come a time when 650' horizontally in 12 minutes may be something I'm pleased with (and that also maxes out my heart rate), but I'm not there yet....
According to the ISOM guidelines, 650' horizontally through dark green should take around 12 minutes for the fittest in the world.
