I'm thinking I ought to start working a little harder in tougher gears and get my speed up a bit... I'm 80% sure I have what it takes to get that 100 miles done. I'm just not sure if my speed is going to cut it though.
I'd be weary of drastically changing how you ride without training up to it. Going out too hard may mean not leaving enough in the tank for the end of the ride.
