Training for the Highlands

Just wondering what you guys think of this kind of hill repeat around Arthur's Seat in Edinburgh.
It's 3 miles, varying from about 5-6% to about 10%. It's the steepest hill near me that has little traffic. I did a few laps last night, and it was tough on my hybrid. It's nothing compared to the Lecht which is about 20% I believe, but that's the kind of thing I'm building towards. I'm just curious how well this kind of route will prepare me for a tour in the Highlands next summer.
