I'm not a fast hiker. I've set a goal: I won't stop dayhiking Whitney until I can do it 10h car-to-car.
That's impressive. I include you in a group I call "Super-Hikers". My last trip down the Main Trail took me 6 hours. No one passed me and I passed several hikers.
I consider you a "fast hiker". Maybe my age (65) influences my judgement.
Congrats on another summit! How many times have you been up there?
