The other ladies here would know better than I would, but since I'm new to cycling and also training for my first century, I thought I'd throw my two cents in. I started cycling in May and signed up for a century happening in mid-August. I personally felt that it was enough time to train and work on gradually increasing my mileage. I see that Livestrong is on September 9th, IMO that would be cutting it short as far as time to train and then tapering off the week before, but someone else might not agree.
