I'm thinking of joining in my husband's first century October 12th. I've been "semi-training" up to this point because I didn't think I could do it on my hybrid, but it looks possible on my new street bike. We ride 16-20 miles a day, 5-6 days a week. We "go long" on the weekends on the Katy Trail near our house (rail-to-trails, fine pea gravel surface). Last month we did a two-day ride that was 44 miles each way.

My plan would be:

week 1/35 miles
week 2/45 miles
week 3/55 miles
week 4/65 miles
week 5/75 miles
week 6 REST
week 7 CENTURY

Any opinions? Advice? Suggestions? Concerns? Tell me I'm crazy?

I can't seem to find much on training plans for centuries (there are a million marathon training plans out there!) My husband's plan was to ride as far as fast as he could and I've been trying to reign him in (he finally took a HR monitor on his hilly ride this morning and I made him take a rest day last week).
