A big thing that I think gets forgotten about is your nutrition and hydration the days leading up to the Century. I paid alot of attention to this and I think it really helped me get through the ride. I started to increase my carb intake 3 days ahead of my century. On the ride I made sure to drink every 20 minutes with sodium, magnesium, potassium electrolyte replacement tabs in my water and then eat every hour even while on the bike.

Make sure you keep your heart rate in a comfortable zone the entire ride so that you don't bonk. I think the recommendation is 75% of your maximum heart rate. I was passed early in the ride by alot of riders only to pass them back in the 2nd half of the ride because they overdid it, weren't hydrating or eating properly and were cramping. So setting a comfortable pace is important as well.

Most of all have fun and enjoy it.
