Yesterday I went out for my longest ride yet, 38.5 mi in 2 hours, I usually ride 20 miles in an hour and a half so this was quite a bit faster than I am used to. It was mostly rolling steep hills, which really slowed me down(I'm on a recumbent and I'm not a very strong climber yet). I was out with a group and I did fine for about 3/4's of the ride, then I just lost all my energy, I was getting farther and farther back from the remaining three people I could see and I just couldn't put out anything more. I finally caught up with them but it took about 5 miles of chasing them.
The ride left at 6pm and at that point all I had eaten was two slices of pizza at about 4 oclock. My legs weren't filled up with lactaic acid or anything, but I just didn't have any steam left. I'd been drinking water regularly(it was pretty hot though about 85 or 90 in full sun for the most part).
Could my low energy levels been due to a lack of food in my belly? I am going out to do the ride again today and I'll try and keep up the same speeds, should I eat something as I go?
I am trying to gauge whether or not I am ready to do the Blackberry Bramble, a full century, it is in about 2 weeks. I am going to go out with the group again for a flat 70 miler. If I can do that, I know that a century is do-able.
The word you're looking for is "bonk".
You ran out of glycogen in your blood. When that happens, your body drastically reduces the amount of muscular effort you can put out so your brain can still get enough glycogen.
The cure is to take in calories as you ride. Some riders use energy drinks, some use gels, some use high-carb real foods. What you use is a personal choice, but whatever you do, you should aim for something like 250-350 calories per hour. Your body can't digest more than that, and if you eat more than that, you may get the dreaded "GI upset".
If you need to buy something quick, fig newtons are common choice, as are sports bars.
That you caught up probably means you didn't have a "hard bonk", which generally leaves you unable to chase (or ride, have a coherent thought, etc.)
Your goal on the 70 should be able to finish without feeling like you're dead. If you can do that, you should be ready for the century.
What I got out of your post was that you rode at 19+ mph average with hills that you are not accustomed to without any supplemental calories on the ride.
If you want to finish a century, you need to slow down and eat more.

If 38 is tough, and the ride itself is two weeks away, you might have difficulty with the full distance (especially if it's hilly)... you definitely need to find a way to get the calories and electrolytes in over the course of the ride.
And it seems like that's around 13 miles an hour average, which comes to 7 and a half hours to finish. What's the longest time you've spent in the saddle?

about 4 hours of me and my buddies cruising around going maaaaaaaybe 10mph. I ride a recumbent though, and I've never had any problems with soreness or any of that. If it is flat I know I can do it. I'm going to do this 70miler on Sunday and see how it goes, if I do okay I'm doing the century, it may take me forever, but I"ll do it.

In other words, your training is so screwed up - that it doesn't matter what you eat.

You need to understand that the effects of going on longer rides will take more time for your body to rest and reload for your next ride. Read more.
