What did I know about packing for a bike tour? Nothing.

Weeks before embarking on my first bike tour, five days through the Mid-Atlantic states, I started a pile on my bedroom floor. Each time I thought of something else I'd need, I threw it onto the pile. If I wasn't home, I'd add the item to a checklist that grew to two pages. I also cross-referenced my thoughts with some expert recommendations (Adventure Cycling Association offers a good list). Finally, I had to face the task of seeing how much would actually fit into the two rear panniers I planned to mount on my bike. (A trailer would have been another option, but I liked the idea of having everything I needed on my bike—and disliked the idea of pulling the extra weight of the trailer itself.)

In addition to the means of conveyance, a few other decisions determined my eventual load: food and accommodations. My route would follow a well-populated path through Pennsylvania, New Jersey, and New York, so stores and restaurants would be easy to find. Other than a few emergency snacks, water, and an admittedly hefty jar of Nutella (which, delightfully, would improve several meals during the trip), I'd buy everything I needed as I went. I still wanted to be as self-supported as possible, though, so my next decision balanced out those weight savings: I decided to camp, rather than check into motels each night.

Finally, just four days before I would be driving down to Philadelphia to start the trip, I assessed the pile. With a quick pass through the gear, I eliminated 4.5 pounds of extras and spares: shoes, tires, clothing. I crammed the rest into the panniers and set them on my scale: 46.75 pounds. There are no hard and fast rules about how much to carry—fitness level, terrain, and trip length are all variables in the equation—but this seemed like too much.

I sorted through the gear again and, like a backpacker, looked for items with multiple uses, and others that I could eliminate. A bungee to fasten my tent to my bike rack could also be a clothesline at night. A detachable bike headlight could double as a reading light. Another sorting eliminated more extra weight, leaving me with 39.5 pounds of gear to carry on a 31-pound bike.

Any experienced long-distance cyclist would recommend going for a lengthy test ride with all my gear (several did, in fact, give me this advice). Or, better yet, go for a short overnight trip before my longer trip, to get a sense for what I'd really need (and not need) to carry. I'd given a lot of thought to my plans, but hadn't scheduled either of the above, settling instead for a short ride just 48 hours before heading to Philly.

With the panniers clipped to the rack over my bike's back wheel and a tent and sleeping pad bungeed on top, the entire set-up felt distressingly heavy. "If I can't lift it all easily—I mean really easily—then I know it's too much," Julie Huck, a staffer at Adventure Cycling, had told me earlier that week. I'd failed that test. As I swung one leg over the bike and prepared to push off, the entire rig swayed uneasily, ready to capsize at the slightest shift in weight. Yet as I began pedaling, I quickly found my balance. Once up to speed, I barely noticed the extra weight, except on the hills.

The final step was to pack my gear as efficiently as possible for the trip. I sorted most items into Zip-Loc bags, and began stuffing them into the panniers. Heavier items went on bottom (for balance), and items I might need during the day—snacks, rain gear, tools—on top.

By the end of my 5-day trip, I was pleasantly surprised by how prepared I'd been. Only on the steepest hills (of which there were, admittedly, several) was my load a challenge, and there proved to be little on my bike that I hadn't needed. I fortunately didn't need any of my cold-weather gear or bike tools—but wouldn't have considered leaving any of them behind. Almost everything else was a welcome presence in my panniers—especially the Nutella. Below is a list of everything I packed.
