Zondian,

No one else has picked up on this, but didn't you mention in the welcome thread that you have only been riding for a month? If I read this wrong, then please ignore this!
But if I read this correct, you might want to either give yourself some more time before you tackle a century, or see if there is a shorter option that you could ride instead.

I do not want to seem negative in any way, but a century is a long distance, and if you have upped your mileage that fast, it could lead to injury or at the very least a very unpleasant ride that could taint your opinion of centuries in the future.

again, if I read that other post wrong, then please ignore this!!
