The first time I unrolled my sleeping bag on a patch of dirt behind a state park campground, the sky was the deepest black I had ever seen. I lay there for what felt like an hour, listening to an owl, the soft pop and hiss of distant highway tires on warm asphalt, and the strange, papery rustle of oak leaves that I could not see. My neck hurt. The ground under my hip was not flat. I was wearing every layer I owned and still felt a thin line of cold air working its way down my collar.
Then I slept harder than I had in months. And when I pedaled home the next morning, with the sun still low and the dew soaking my shoes, I understood why people keep doing this. This is what it is really like to sleep out on a sub-24-hour overnight ride, also called an S24O: short, awkward, slightly uncomfortable, sometimes magical, and almost always worth it.

What Is a Sub-24-Hour Overnight Ride?
A sub-24-hour overnight ride (S24O) is a short bikepacking trip where you load a bike with the bare minimum of camping gear, ride to a campsite, sleep outside, and ride home, all within a single 24-hour stretch. The term was coined by Grant Petersen, founder of Rivendell Bicycle Works, in a 2007 essay, and the bike community has been arguing about what counts ever since.
The hard rule, if there is one, is that the whole thing, from leaving your house to getting back, must take less than a day. A 6 p.m. Friday departure and a 10 a.m. Saturday return counts. A Friday evening start and a Sunday evening return does not. That is just a regular overnight trip.
The S24O is a specific flavor of microadventure, designed for people with real jobs and limited vacation time. The point is not to set a mileage record or push your limits in the wilderness. The point is to get outside, sleep on the ground, and be back in time for Saturday lunch.
How an S24O Differs From Regular Bikepacking
A weekend bikepacking trip usually involves detailed route planning, resupply stops, multiple campsites, and a heavier load. An S24O strips almost all of that away. You pick a state park or hiker-biker site 20 to 60 miles from home, pack a small bag, and ride out the door after work on Friday.
The trade-off is that an S24O is not really an expedition. It is a backyard campout on a bicycle. That is the entire appeal. The bar to entry is so low that the only real obstacle is deciding to go.
The Ride Out: Friday Afternoon and Evening
Most S24Os start on a Friday afternoon, around 4 or 5 p.m. You have just finished the work week, the bike is already loaded, and the goal is to reach camp before dark. The actual distance you cover depends on terrain, but for most riders, 20 to 50 miles one way is the sweet spot. That gives you two to four hours of riding, leaves time to set up camp, and still puts you in bed by 10 or 11 p.m.
The first 10 miles feel strange. Your body is still in work mode, your legs are stiff, and you keep thinking about the email you forgot to send. By mile 20, something shifts. The road noise fades, the air cools, and you startle a heron out of a roadside ditch. By mile 30, you are no longer thinking about work at all. You are just riding.
If you are doing this in summer, the sun sets late, around 8:30 or 9 p.m. in much of the Northern Hemisphere. That gives you a long twilight and a soft, blue half-light for the last few miles. It is one of the best parts of the trip, that last hour of riding when the day finally lets go.
If your route includes any night riding, expect a different kind of focus. A good front light and a steady red rear light are non-negotiable. The road feels narrower in the dark, even on a familiar route. Sounds get bigger. Every owl sounds like it is six feet away.
Arriving Tired, in the Best Way
By the time you reach camp, you will be tired, but not the kind of tired that comes from a stressful week. This is the kind of tired that comes from using your body for what it was built to do. You have been outside for hours, you have used your own muscles to cover the distance, and you are exactly sleepy enough to fall asleep fast.
This is, in my experience, the single biggest advantage of an S24O. The sleep is almost guaranteed to be good, because you earned it.
Arriving at Camp: The First 30 Minutes
Most state park hiker-biker sites are simple: a small cleared area, a picnic table, sometimes a fire ring, and a bear box for food. Some have potable water. Some have a pit toilet. The good ones are tucked back from the road, surrounded by trees, and quiet after 9 p.m.
The first 30 minutes at camp follow a pattern. You lock up the bike, drop the bags, and walk the site to pick a flat spot for your sleep system. You do not need much space, a 6-by-8-foot rectangle is plenty for a bivy or a small tent. The ground is rarely as flat as you want. You will move your pad at least twice before you commit.
Then comes the small ritual of setting up. Air goes in the sleeping pad. The bivy unfolds, or the tent poles click into place. The water bottle goes in the bear box, or hung from a tree branch if the campground uses those bear cables. Your phone goes on airplane mode, because there is no signal anyway.
You notice how loud the woods are at dusk. Crickets, frogs, the high, thin whine of mosquitoes. A couple of crows arguing in the canopy. The first time I heard all of this, I was convinced someone was playing music a long way off. It was not music. It was just the woods being the woods.
The Sleep Experience: What 2 AM Really Feels Like
Here is the honest part. Sleep on an S24O is rarely eight perfect hours. It is more like four to six hours of surprisingly deep sleep, broken up by the kinds of small wakings that do not happen at home.
The first wake-up is usually around midnight or 1 a.m. You stir because your hip is sore, or because you can hear footsteps outside. (They are almost always raccoons. Sometimes they are mice. Once, on a trip in Minnesota, they were a family of curious cows that had wandered over from the next field.) You adjust your bag, check that the bike is still locked, and go back under.
The second wake-up is around 3 a.m. This is the one nobody warns you about. The temperature has dropped, the stars are doing their thing, and your mind gets surprisingly awake. You lie there for 20 or 30 minutes, listening to the wind in the trees, and you think about nothing in particular. It is not unpleasant, exactly. It is just a different kind of consciousness than you have at home.
Then the cold finds the one place your sleeping pad has compressed. You shift. You re-inflate the pad with a couple of breaths. You pull the hood of your bag a little tighter. And you go back to sleep.
By 5:30 or 6 a.m., the birds take over. The first thing you hear is usually a wood thrush, then a towhee, then a whole dawn chorus that builds for 15 minutes. The sky lightens from black to gray to soft blue. The air smells like wet leaves. This is the second-best part of the trip, after the first hour of riding the night before.
Realistic Sleep Duration on an S24O
Based on my own trips and conversations with other riders, plan for five hours of actual sleep, not eight. That is the realistic number. You will not be doing REM math in the morning. You will be tired in a way that feels good.
One Reddit rider put it better than I can: “Turns out 100km and 1000m elevation helps with sleep a lot.” The exhaustion is the point. You are not trying to replicate the eight hours you get in your bed at home. You are giving your body a different, more primal kind of rest.
Night at Camp: Between Arriving and Sleeping
There is a stretch of about two hours on an S24O that nobody talks about in the guidebooks, the time between arriving at camp and actually falling asleep. This is the campfire hour, the cooking hour, the small rituals that turn a patch of dirt into a temporary home.
If you brought a stove, dinner is usually simple. A gas station burrito eaten warm from the pot. A dehydrated meal that takes eight minutes and tastes better outside than it ever will at your desk. A piece of bread, a piece of cheese, an apple. The food is rarely the point. The cooking is the point.
If there is a fire ring and firewood, the campfire becomes a small stage. You sit on the picnic table or on the ground, and you watch the flames. The smoke keeps the bugs off. The heat pushes the chill out of your hands. Other campers might walk by, say hello, ask where you rode in from. Sometimes that becomes a 20-minute conversation. Sometimes they just nod and move on.
After dark, the world shrinks to the circle of your headlamp. You wash your face with cold water. You brush your teeth. You realize you do not actually need to do anything else. There is no email to answer, no laundry to fold, no TV to watch. There is just the fire and the dark and the slow business of getting tired.
Wildlife and the Small Noises
Wildlife is rarely a problem on an S24O. State park campgrounds are usually too busy and too close to people for big animals. Raccoons are the most common visitor. They will steal food if you leave it out, which is why the bear box matters. Mice will investigate your handlebar bag if you left crumbs in it. Owls will call from somewhere overhead.
The one animal nobody warns you about is the fox. If you are lucky, you will hear one bark at 2 a.m., a single sharp yip that sounds wrong, almost mechanical. It is not a threat. It is just a fox being a fox.
The Morning After: Riding Home
Dawn at camp is the second-best part of the trip, after the first hour of riding out. The light comes in low and sideways, the dew is on everything, and the air smells like wet pine and woodsmoke. If you slept through the night, you wake up feeling loose, hungry, and a little surprised that you are still on the ground.
Breakfast is usually coffee if you brought a stove, and a bar, and water. You pack up the sleep system first, then the shelter, then the food bag, then check the site for anything you left behind. The pad is damp, the tent is damp, everything goes in the bag a little wet. That is fine. It will dry when you get home.
The ride home is its own reward. The road feels different at 7 a.m. than it did at 5 p.m. the night before. The shoulders of the road are full of small birds. The towns you biked past in the dark are suddenly full of detail. You notice a hardware store, a bakery, a long row of mailboxes. The world is awake and you are already an hour into your day.
You will probably get home around 9 or 10 a.m., earlier than almost any other weekend camping trip would allow. There is time for a shower, a real breakfast, and a nap before the day is half over. The bike is dirty. The bags need to dry. You are already thinking about where to ride next weekend.
What Gear You Actually Need
You do not need much for an S24O. After a few trips, most riders cut their gear list in half. The first time out, I packed like I was going on a week-long tour. By the third trip, I had a small dry bag with everything I needed, and it weighed less than 10 pounds.
The minimum viable setup is a sleep system (sleeping bag or quilt, sleeping pad, optional bivy or tent), a water filter or extra bottles, food, a light, a layer for sitting around camp, and a small first-aid kit. That is it. Everything else is optional.
The sleep system is the part to invest in. A good sleeping pad, the kind that keeps you off the ground and insulates you from the cold seeping up through the dirt, makes a much bigger difference than a fancy tent. A 3-season quilt rated to 30 degrees Fahrenheit is enough for most summer S24Os. In shoulder seasons, you will want a warmer bag and an extra layer.
For shelter, a bivy sack (a waterproof, breathable cover that goes over your sleeping bag) is the lightest option and the most weatherproof for the size. A floorless tarp is lighter still and gives you more space to sit up and cook. A small one-person tent is heavier and bulkier but feels more like home. There is no wrong answer.
On the bike, you have three main packing options: a frame bag in the front triangle for tools and small items, a handlebar roll for the sleep system, and a small seat pack for the food and water. A rear rack with a single pannier works fine too, especially for a commuter or gravel bike that already has rack mounts.
The Gear Most Riders Forget (or Overpack)
Everyone overpacks for their first S24O. The list of things I brought that I did not need is long and a little embarrassing. A camp chair. A pillow (a stuffed jacket works fine). A book. A second pair of socks. A coffee press. A backup flashlight. A folding shovel. None of it got used.
The list of things I forgot that I actually needed is shorter. A proper water filter. A warm hat for sleeping. A spare tube that fit my actual tire size. A trash bag for keeping my wet tent separate from everything else. Toothpaste.
After three or four trips, the gear list writes itself. The goal is not to have less stuff. The goal is to have exactly the right stuff, and to know where it lives on the bike.
Common Fears and Why They Fade
The most common question riders ask before their first S24O is some version of, “Does it feel sketchy?” The short answer is yes, the first time, and no, after that. The longer answer is that the sketchiness fades faster than you would expect.
The fear is real and it is worth taking seriously. Sleeping outside, alone, in the dark, after a long ride, is a vulnerable thing to do. Your senses are sharper. Every noise is louder. The woods are full of small movements that you cannot identify. None of this means you are in danger. It just means you are paying attention in a way that modern life rarely asks you to.
What changes after a few trips is not the environment. The raccoons are still there. The owls still call. The 3 a.m. wake-up still happens. What changes is your relationship to those things. The unknown rustle in the leaves stops being a threat and starts being a detail. The cold stops being a problem and starts being a sensation. The dark stops being something to push through and starts being a place to be.
This is, I think, the part that does not show up in any gear list or route map. An S24O is a small, low-stakes training ground for being uncomfortable on purpose. You learn that you can sleep somewhere strange, that you can wake up in a place you do not know, and that the world does not end. After a few trips, that lesson follows you home. You sleep better in your own bed. You handle stress at work differently. You stop needing the world to be perfectly controlled.
The Sketchy Factor for Women and Solo Riders
For women and solo riders, the fear is not abstract. It is specific, and it is reasonable. The good news is that state park hiker-biker sites tend to be busy enough that you are not alone, but quiet enough that you have your own space. Most of the people you will meet are also there to sleep and not be bothered.
If you are nervous, ride with a friend the first time. Pick a state park with a camp host and a fee station. Tell someone where you are going and when you plan to be back. Carry a small personal locator beacon if it makes you feel better. None of this is overkill. It is just good practice.
Why the S24O Is Addictive
After your first S24O, you will probably want to go again within two weeks. This is normal. The S24O is a tiny adventure, but it works on the same parts of the brain as a week-long tour, with a fraction of the planning and a tenth of the time off work.
The first time I came back from an S24O, I sat in my driveway for 10 minutes before going inside. The bike was filthy. My legs were sore. I had a bug bite on my ankle and a small hole in my jacket. I felt better than I had in a month.
That feeling does not go away. It just gets easier to reach. An S24O is the smallest unit of bikepacking that still feels like bikepacking. Once you have done one, the next one is just a matter of picking a Saturday and a state park.
FAQ: Common Questions About Sleeping on an S24O
How do you actually sleep while bikepacking?
You sleep on a small inflatable sleeping pad laid on the ground, inside a sleeping bag or quilt, with an optional bivy sack or tarp shelter above you. Most S24O riders get 4 to 6 hours of real sleep, broken into two or three short sessions, not a single 8-hour block.
Is it realistic to bike 20 miles a day on an S24O?
Yes. A 20-mile one-way ride is one of the most common S24O distances, and many first-timers start with that exact number. It is short enough to leave after work, long enough to feel like a real ride, and easy to extend to 30 or 40 miles once you have a few trips under your belt.
Is it possible to bike 200 miles in a day on a sub-24-hour overnight?
Not really, and that is the point. An S24O is capped at under 24 hours total, so a 200-mile day would leave you almost no time to set up camp, eat, and sleep. Most S24O rides top out around 50 to 80 miles one way for very strong riders, and 20 to 50 miles for everyone else.
How long do riders actually sleep on a sub-24-hour overnight?
Plan for 4 to 6 hours of actual sleep on an S24O, split into 2 or 3 sessions. You will not sleep 8 uninterrupted hours like you do at home, but the sleep you do get is usually very deep because of the physical exhaustion from riding all day.
Is it safe to sleep outside alone on a bikepacking trip?
For most riders, in a state park or established hiker-biker site, yes. The main risk is wildlife (mostly raccoons and mice) and minor inconveniences like cold or a lumpy patch of ground. Tell someone your route, carry a small first-aid kit, and you will almost certainly be fine.
Final Thoughts: What to Expect on Your First S24O
If you are planning your first sub-24-hour overnight ride, the most useful thing I can tell you is that the experience is not what you are imagining. It is smaller, slower, and more ordinary than the bikepacking photos suggest. You will be tired. You will be a little cold. The ground will not be flat. You will wake up twice in the night and wonder why you are doing this.
And in the morning, when you ride home with the sun in your face and the dew on your shoes, you will already be planning the next one. That is the part of the S24O that no gear list can sell you. It is a small, repeatable adventure, and once you have done it, the weekend opens up in a way that it did not before.
Pick a state park 30 miles from your house. Load the bike on Friday afternoon. Ride out the door. Sleep outside. Come home Saturday morning. That is what it is really like to do a sub-24-hour overnight ride, and that is all there is to it.
