You definitely can do this. Go at it and see how far up you make it. I'll bet you can do the whole thing.

Keep the gear just easy enough that you can keep the cadence up. When the cadence falls, downshift a gear, repeat, etc. But probably you want to start with the same chain ring as you will finish in - going up cogs is easy, shifting the FD under load is tough.

Consider standing for part of the steepest parts, or alternate standing and sitting.

Don't skimp on hydration and don't do it in the serious heat. If summer comes early to W. PA, do the hill in the early morning before it gets too hot.
