Six in the morning, the last Saturday in May, and the prairie is still dark. A few thousand head units glow blue in the dew. Out past the edge of Emporia the gravel is already waiting — tallgrass laid over a bed of broken flint, two hundred miles of it, and not one rider on that start line has raced the road they're about to ride. Then the gun goes, and the Flint Hills get to decide who the start list was really talking about.
That's Unbound. The biggest gravel race on earth, and it never quite knows what it is until it starts. Every year the entry list in Emporia reads like a WorldTour transfer window crashed into a privateer reunion. Every year the Flint Hills sort out which of those names actually mattered. This Saturday, 30 May, the question is sharper than it has ever been — because the organisers have built something they've never built before, and the sky has been doing something it hasn't done in years.
The course is new. The 200-mile elite race has always run as a north loop or a south loop out of Emporia, one or the other. For 2026 they've sewn the two together and taken the best of both — or the worst, depending on whose legs you ask. It comes out at 207 miles. Call it 333 kilometres, with more than 9,000 feet of climbing, a brand-new third checkpoint, and sectors that haven't carried a race number in over a decade.
And it has been raining. Most days of the build-up. May is the wettest month in this corner of Kansas — around 118mm on average, highs near 24°C, lows close to 13 — and the forecast has been a wall of little cloud icons all week. The Flint Hills need no encouragement to turn vicious. 2015 was a mud year. 2023 was an epic. The riders are packing like 2026 could be a third.
So treat this as a different kind of preview. Not a betting card. A look at what makes this Unbound its own animal — the course, the field, the kit, the fuelling — and at what a 207-mile day on Kansas dirt can teach you about your own riding, whatever you're building toward. Because the lesson at the sharp end of this race is the same one waiting on your next long day out.
The course: a route no one has ridden
Emporia is a college town of 24,000 that becomes the centre of the gravel universe for one weekend a year. Nobody comes for the town. They come for the roads. The Flint Hills are tallgrass prairie stretched over exposed flint — chert rock, hard and sharp, half-buried in the dirt and scattered loose on top of it. Beautiful and hostile in the same breath, the way some things manage to be both. Windblown plains. Creek crossings. Climbs that are never steep and never stop.
That last part is what catches road riders out. No Alpe d'Huez here. No gradient steep enough to make you change your whole position on the bike. What you get instead is a relentless conveyor of rollers that empties the legs by attrition. Never steep, always there. Crest one and you're already dropping into the next, and by hour eight their cumulative weight is the climbing that counts — far more than the elevation number ever lets on.
The hybrid route drags back terrain that Unbound regulars only mention in a slightly lowered voice. Texaco Hill and Teeter Hill are on the menu. So is the Kahola dam. And the big one — a 10-mile stretch of Sharpes Creek Road, a sector last raced in 2015, which was, not by accident, the most notorious mud year in the race's history. Putting it back in a year with rain on the radar is either confidence or mischief. It's probably both.
Everyone who's pre-ridden it reaches for the same three words: chunky, rocky, potentially muddy. The flint punishes a careless tyre choice. The creek crossings run ankle-deep or axle-deep depending on the week. And mud at Unbound isn't the slick, wash-off kind — it's peanut butter, the sort that packs into a drivetrain and stops the wheels dead. In 2015 riders carried their bikes for miles. The ones who finished had clearance, and the heads to accept early that this was going to be that kind of day.
The new third checkpoint matters more than it reads. Checkpoints are where Unbound is genuinely won and lost — the only places your drop bags are waiting, the only sanctioned spots to refuel and fix things across a self-supported day. A third one rewrites the rhythm of the race and the arithmetic of what you carry between them. Get the spacing wrong in your own head and you'll run dry in the gap.
Race morning, the elite men roll out at 6:00am CDT, the elite women at 6:05am, into the dark and the dew. Behind the 200-mile race sits the 350-mile XL for the genuinely unwell, plus 108.5, 56.8 and 26.6-mile distances for everyone else. Tens of thousands of riders. One set of roads. One very long day.
For the full picture of how to physically build toward a day like this — the back-to-back long rides, the over-distance ride, the drop-bag logistics — we've laid the whole thing out in the Unbound Gravel 200 training plan. This piece is about the race itself.
Who to watch: the men's field
Start with the man who set the bar so high nobody has reached it since. Cameron Jones, 24, the New Zealander on Scott-Shimano, won here in 2025 in 8:37:09 — the fastest the 200 has ever been ridden, and it isn't close. He and Simon Pellaud went clear with roughly 150 miles still to go, rode the rest of the day as a two-man committee, and Jones kicked away in the final miles. He comes back as defending champion and the form rider. There is no version of this race where he isn't near the front.
Simon Pellaud is the man he beat. The Swiss spent that day doing most of the work and lost it to a sprint — and a rider who came that close, having paid that much for it, does not tend to come back quieter. He races on instinct and aggression. Expect both.
Then there's Lachlan Morton. The EF rider won Unbound in 2024, out-sprinting Chad Haga after the pair of them had already torn the race to pieces, and he's a factor over this distance every single time — he's spent years proving he's at his best when the day is longest and the script is thinnest. When Lachlan came on the podcast and talked through his evolution as an athlete, that was the whole throughline: he's pulled toward the events where endurance and self-reliance beat a sprint train. Unbound was built for that head.
Keegan Swenson is the other name you can't ignore. America's most decorated off-road racer spent two weeks in what he called hermit mode at altitude in New Mexico, rebuilding from a hip injury he'd been managing in Spain over the winter. He's reportedly riding in tandem with Matthew Beers. A Swenson who turns up healthy and sharp is a problem for the entire field — the engine to make the selection, the savvy to ride the back half clever.
After that the threats come fast, and this is genuinely the deepest the men's race has ever been. Romain Bardet, the former WorldTour climber, has crossed to gravel cleanly with multiple wins and the patience a long day rewards. Lukas Pöstlberger arrives off a win at the Traka 200, with the kind of form that travels. Bradyn Lange took the 2025 US Gravel Nationals and opened his 2026 Life Time Grand Prix with a victory — a young rider climbing fast. Ivar Slik, the first non-American to win the men's 200 back in 2022, is back from a serious injury and knows precisely how to ride this thing. Thomas De Gendt and Mads Würtz Schmidt, both hardened off the road, are built for the long break and will be in it.
And then the story every broadcast will run with: Taylor Phinney, out of a seven-year retirement, lining up at the biggest gravel race on the planet. Whatever he does on the day almost doesn't matter — that's the spirit of the thing. Gravel is where the old road world and the new dirt world keep walking into each other at the coffee stop.
Who to watch: the women's field
The women's race has the better story this year, and it belongs to a German PhD student. Rosa Klöser won Unbound in 2024 in a historic group sprint, came back in 2025, and lost it to a crash and a wrong turn that dropped her to fourth. She's back for the win that got away. She's a CANYON//SRAM WorldTour rider who races road and gravel at the very top, and when Rosa came on the podcast she walked us through the surprisingly simple training that won her Unbound the first time. If you follow one rider this Saturday, make it her.
The obstacle is the defending champion. Karolina Migoń of Poland won the women's 200 in 2025 and turns up off a win at the Traka 360 — proof she's peaking on the longest, hardest gravel days on the calendar. She's the form pick on the women's side the way Jones is on the men's. Migoń against Klöser is the matchup worth getting up early for.
And the depth behind them is real. Paige Onweller has stood on this podium and knows how to be there when it counts. Carolin Schiff, Sofia Gomez Villafane and Lauren De Crescenzo are all former Unbound champions coming back to the same start line — which tells you everything about how hard this win is to hold, and how many riders capable of taking it will be on the same road at the same time.
A field this deep. A course nobody's raced. Weather nobody can call. That's the whole appeal, right there.
Bike tech: the choices that decide your day
This is the part most riders get wrong before they've turned a pedal. The watts barely settle Unbound. A rider on the right tyres at the right pressure, fed and patient, will ride clean away from a stronger rider who sliced a sidewall at mile 80. Your setup isn't the boring admin before the race. It is a large part of the race.
Tyres first, because at Unbound tyres are everything. The standard is 40-45mm tubeless, and 700x45 is the common race setup across the front of the field. In a wet or muddy year the Schwalbe G-One Ultrabite is the popular pick — an aggressive tread that sheds mud and finds grip when the road turns to paste. The flint is the enemy. Light cross-country casings get shredded inside the first 50 miles, and a sliced sidewall in the back half is the most common way a good day ends early. Casing protection is the cheapest insurance you'll ever buy. Buy it.
Pressure is where riders overthink and underthink in the same breath. A workable starting point on a tubeless setup is your weight in pounds divided by 7 for the rear psi, then drop 2-3 psi off the front. A 160lb rider lands around 23 rear, 20 front. Go too low and you start striking the rim on the rocks. Go too low up front and the tyre burps air on the hard hits. That's exactly why tyre inserts have gone from niche to near-standard — they let you run the soft end of the range for grip and comfort over 200 miles without paying for it with a rim strike or a burp. Insurance again. The pattern repeats all day out here. Find your number on rough ground at home, not on the start line. Our full tyre pressure guide walks through how casing, surface and weight move it.
Then the drivetrain argument, which never ends and never will. Since 2021 the winners have split almost exactly 50/50 between 1x and 2x — which is the most honest answer anyone can hand you about which is better: it depends on the rider. A 1x setup, something like SRAM RED AXS XPLR with a 50T chainring and a 10-46T cassette, is simpler, lighter, and clears mud better because there's no front derailleur to pack solid. A 2x, say a Shimano Ultegra 52/36 up front, gives you tighter steps between gears and smoother shifts when you're holding a precise effort for hours. A mud year leans you toward 1x for the clearance. A drier, faster year, where you're fighting to hold a wheel at 23mph, leans you toward the range of a 2x. Both win races. Pick the one that fits the day you're expecting and the legs you've actually got.
Fuelling 200 miles: the real engine
If your tyres decide whether you finish, your fuelling decides what kind of rider crosses the line. Unbound is a calorie deficit dressed up as a bike race. You cannot eat what you burn across twelve-plus hours, so the whole game is shrinking the gap and protecting the gut that has to keep absorbing food while you bounce over rock.
The target is 80-120g of carbohydrate an hour, from the gun. That's a lot, and the only way most riders hold it down that long is to take half of it as liquid — a carb drink mix doing half the work while you chew the other half. On rough ground that's not just a gut call, it's a handling one: far easier to keep drinking through a chunky sector than to unwrap and chew a bar with both hands busy keeping the bike upright. Eat something every 30-45 minutes and you keep the tank topped instead of chasing it empty, which never works once you're behind.
Electrolytes are not optional in Kansas. Sun plus carb solution alone, hour after hour, will turn your stomach and cramp your legs — a high electrolyte mix is what keeps the whole system running. On a hot, exposed course with no shade to hide in, the sodium you're shedding is enormous, and a gel won't touch it. The old Texan rule still holds: if you're not peeing every couple of hours, you're behind on fuel, fluid, or both.
The course hands you a rhythm to plan around — water roughly every 40 miles, full support stations roughly every 80 — but the riders who do well treat the official supply as a backstop, not a plan. Your own bottles. Your own drop bags at the checkpoints, pre-packed and rehearsed. Both faster and more reliable than queuing for someone else's.
And the rule sitting under all of it: test everything in training first. Race day is not the morning to learn that your gut hates 100g an hour. We go deep on all of it in the in-ride nutrition guide, and on hitting those numbers without blowing up in carbs per hour for cyclists. If you want to hear how badly the sport got this wrong for years, the World Tour nutritionist episode is the one — the pros under-fuelled for a decade before they worked out what plenty of amateurs are still getting wrong today.
Race-day intel: how to survive the day
Whatever happens at the front, the back half of Unbound is a survival exercise for almost everyone on the road. The riders who manage it well share a handful of habits, and not one of them is complicated.
Pace your own effort, not the rider in front. That's the single most important sentence in this whole piece, and it holds at every level of the race. On a course of 200-odd rollers, the temptation is to surge over each one to stay glued to a wheel. Don't. Stand and punch every roller and you spend a currency you can't earn back, and by the third checkpoint the bill arrives. Sit. Hold your endurance effort. Let the gradient pass under you. The same discipline that wins a long climb wins a long gravel day — ride the climb, not your rivals. We pull the psychology apart in how to stop getting dropped on climbs and pacing strategy for long climbs, and it transfers straight onto the Flint Hills.
Plan for mud, hope for dust. With rain all week, the smart riders are arriving with a full mud plan and ready to be pleasantly surprised if they never need it. Clearance. A tyre that sheds. A willingness to run a packed sector rather than ride it. And the mental acceptance — early, before it happens — that a slow muddy mile is still a mile done. The riders who come apart in the mud are nearly always the ones who spent the first hour of it furious.
Respect the heat even on a wet day. Highs near 24°C, Kansas humidity, and next to no shade across the prairie add up over twelve hours even when it isn't a scorcher. If your training has been cool and grey, the first long hot day is the one where things quietly fall apart. A little heat preparation in the final weeks pays for itself many times over, and a real hydration plan is the line between fading and finishing.
Run your checkpoints like a pit stop. Refill, swap the drop bag, eat something solid, leave. Sit down for a chat for 25 minutes and your legs stiffen, your body cools, and the restart costs you more than the rest ever gave you. The new third checkpoint this year is one more chance to get this right. Or one more chance to get it wrong.
None of this is exotic. It's the craft of riding far over rough ground — the thing the French call le metier, the unglamorous, learnable trade of being a cyclist who finishes. The strongest engine in the world loses to the rider who fuels, paces and packs better. That's the most democratic thing about Unbound, and the most useful thing it has to teach you.

What this means for your own riding
You're probably not on the start line in Emporia on Saturday. Doesn't matter. The point is that the biggest race in gravel comes down to exactly the things that decide your own long days — and the gap between you and a finisher is almost never the headline number you keep staring at.
It's whether you matched your tyre and pressure to the ground. It's whether your gut can take 80g an hour because you trained it to. It's whether you can sit on your own effort while everyone around you burns matches they haven't got. All three are learnable. All three are, to use the only honest word for it, fixable.
If you've been training hard and your long rides still come apart in the back third — legs gone, stomach turning, wheels drifting up the road — that's not a verdict on your fitness. It's usually a structure problem, and structure is something you can fix. The fastest way to find your own leak is the free Plateau Diagnostic: a few honest questions about how you train, fuel and recover, and a clear read on the one thing holding you back.
Whatever the Flint Hills decide on Saturday, the riders who do well will be the ones who prepared for the day they couldn't predict. That's the whole game — on Kansas dirt, and on your own roads. You're not done yet.
