Congratulations, Tabriz--that's quite an achievement. I do think you were tempting fate by not following a more formal eating plan. I just completed my first metric century on Sunday, and I spent a lot of time reading posts in this forum, the road riding forum, and the endurance riding forum to learn about in-ride nutrition. I used all the knowledge I gained during my ride and finished feeling pretty good about my state of hydration and nutrition during the ride.
