Thanks for the advice! The century has some climbing, but it doesn't look too hilly- I think under 2000 feet of climbing over the 100 (maybe even closer to 1500). A lot of the gain is one long climb at a lower grade. I'll keep an eye out for the Diablo plan- it sounds good to me.

So, it sounds like I should concentrate more on endurance and let the speed come on it's own. Will it come on its own? It also seems that it may be a good idea to avoid my big climbing rides until after the century and just do more moderate hills. I actually really enjoy the rush of climbing,but it seems that I'll benefit more from base miles right now. Should I worry about monitoring my heart rate at this point? I plan to find my LTHR today, but maybe it isn't relevant yet.

I'm thinking I'll aim for one long ride per weekend (hopefully I'll get at least two 80+ in) and a recovery ride each weekend (25-35 miles or so at a slow pace?). Then during the week, I'll do two days of intervals and one shorter session on the trainer at a faster speed than normal. How does this sound? Also, would it be ok if I do the short slow ride the day before I do the long ride? I generally have a riding partner on Sunday and I think she'll want to do the longer rides.

Thanks again, I've been searching past threads and found a lot, but it's difficult when we all have such different schedules and goals. I guess I also just want confirmation that I'm on the right track. I can't wait till I can say I did a century, too. You guys are great!!
