Excellent! Hills are your friend. Last year I lost 35lbs of bodyweight. I'm after another 10lbs below that this year. Every 2lb loss can be felt on the hills.
Do you have a smartphone with Strava? That is what has helped me on hill-attack runs this year. We have 2 hills that are nasty, almost like a Michigan version of your Snake Mt. When you track your performance and see it improve as you enjoy the summer.....it puts a little zip in the spinning.
Congrats on the climb!
