Yeah, you've got the right idea there. My friend/coworker/cycling buddy was thinking to ride from Kihei all the way to the top of Haleakala and back, but I'm not so keen on the idea. 10,000 feet of climbing is challening enough without adding extra miles and getting hammered by the trade winds on the way there. I want to attack the big hill with a fresh pair of legs!
Speaking of which, I'd invite you to come along on a group ride on Tuesday the 16th but I realize you may not have the time and want to save your legs for the big climb on Wednesday. If your plans change or you'd just like to compare notes and/or B.S. with some fellow cyclists, my # is (two five three) 951-4712.
