People in North America drive them through the Rockies so your hills
will be no challenge. The engine will be loud and you may have the
sensation of a slipping clutch, but these are completely normal in a
Prius.

What I've found is any speed below 65 mph (USA) or 105 km/hr will climb
all day long. However, for efficiency, I prefer to find a fully loaded
truck going up the hill and follow them up at their same speed. I often
use fully loaded trucks as my 'pace car.' I don't follow close behind
but just use them to set my cruise control speed.
What I've also found is this strategy preserves the excellent cross
country efficiency. It seems an efficient climb gets converted into
potential energy very efficiently and then plays out nicely on the
downgrade.
GOOD LUCK!

Rt. 68 in WV?
You'll go up that mountain at 12-15 mph?

Rt. 68 in WV, that doesn't sound like an interstate.
Following trucks up grades works quite nicely on 4-lane, interstate
highways and I notice many of them in mountainous areas have a climbing
lanes, 5-lanes. For example, I-81 between Roanoke and Bristol.

Yup, it is. Interstate 68.
And there's one helluva mountain right there.
