1. Take a step back.

2. Just get started.


Seriously, it sounds like you've got your bases covered. There's no law that says you have to ride clipless, but if you choose not to, I'd recommend using platform pedals and street shoes, not toe clips, which is a whole 'nother learning curve that's actually harder and scarier than clipless. You don't say what kind of riding experience you already have, but if you'll be dealing with a lot of learning curves at once (riding position on a road bike you mentioned, but are you familiar with derailleur shifting, rim braking, looking behind you with or without a mirror, just to name a few) ... then it's probably smart to put off the additional learning curve of clipless pedals. They don't help you go further per se, they help you ride more efficiently, but that's a "want" not a "need" when you aren't racing.

Most of us find that 90 minutes to 2 hours is the longest we can ride efficiently without some calories. How you get those calories is up to you - whether it's solid or liquid, real food or sports nutrition, carried with you or bought along the way. If you just want to have a gel tucked away for blood sugar emergencies, that will fit in your flat tire bag or jersey pocket. Most jerseys have big enough pockets for an energy bar or small sandwich or piece of fruit, whatever you like and whatever your stomach will tolerate on a ride.

You don't mention your inflation system - pumps and CO2 inflators each have their advantage, but make sure you have at least one of those or the spare tube won't do you much good! Personally I carry a spare tube AND a stick-on patch kit, a CO2 inflator with two cartridges AND a very small back-up hand pump "just in case."

I would put on a second water bottle. If you're thinking about going long enough to need food, you'll need more water first. Especially as the warmer months are approaching.

And, have fun!
