I've so been in your shoes. When I first started riding, it was in an effort to endear myself to my then-boyfriend, who was a pretty strong rider. Oh, what folly. One of my first serious rides was 42 miles. With him and only him. On a hot day. The only food I had on me was a Peanut Butter flavored Clif Bar. I wasn't yet adept at drinking from a water bottle while moving, so I got pretty parched during the ride. I finally begged for a break so that I could eat something, but I was feeling so poorly at that point and was so thirsty, that the Clif Bar tasted like dry oats. I couldn't even choke it down. I can barely even look at one now, let alone eat one.

I'm not even sure how I managed to finish that ride; it was a nightmare.
I rethought my strategy at that point (and we broke up not long thereafter) and took a more measured approach. He and I remained friend as it turned out, and I eventually got strong enough not only to keep up, but on occassion to kick his butt! So, we learn from both our mistakes and our victories.
