Mt borah: first time

I would like to try to hike Borah Peak this summer, but am nervous about it. I was thinking about doing it in early september, so I have some time to train.

Ability:
Just got back from Glacier national park including which included a trip over Red Gap Pass (4-16 miles a day, with up 3000 ft of elevation gain per day, all with packs, 7600' max elevation).


Right now we just run around the foot hills near Boise, but we are looking for some good day/overnight hikes close to Boise to get us into better shape and up in elevation before we go up borah.

Any suggestions?
