Sarah, thanks. A little addition info:

1) I have a "power to weight ratio" issue. I am SLOWLY losing some weight, about 6 pounds in the past 6 weeks. Hope to keep that up right through July.

2) I am attempting some periodization by cutting way back on mid-week training time and intensity about every 3rd week, even if the long ride stays long.

3) Due to terrain where I live, as much as anything, I think I will also be alternating longer hilly rides with shorter truly mountain road climbing.

4) I do keep an eye on my HR monitor and gearing...for recovery from efforts...but, sometimes even my 30-32 low gear feels tough! LOL

I really appreciate the encouragement about not giving up on my goal before ride day. Yesterday after the hard climb, I had the choice between going up and over for a shorter, easier route back to my car, or going back down and doing the additional climbing to hit my goal. I told myself I was tougher than that and that I could do it. I felt toasted, but satisfied, at the end of my ride.

It sure helps to hear from those of you who have done a lot of climbing, and trained others. THANK YOU!!
