I plan to do my first century (106 miles) this summer. I know the areas I'll be riding in, though not necessarily all the roads. I'll ride solo as I usually do and have plotted a course around my city so I'm never much more than 20 miles away. I have already purchased 2 Clif bars and 3 packets of goo. Despite the obvious nutrition and hydration requirements, is there anything I should know or consider before embarking?
