Big Sugar Gravel: Training Guide
A hundred miles of sharp Ozark gravel and punchy climbs in the Arkansas hills.
Big Sugar Gravel is the marquee gravel race in the Ozarks, based in the mountain-bike hub of Bentonville, Arkansas, and one of the premier events on the American gravel calendar. The headline distance is roughly 100 miles over chunky, often sharp gravel and a steady diet of punchy climbs.
The difficulty here is less about raw distance and more about terrain and repeatability: the rocks are hard on tires, the climbs come in short steep doses rather than long grinds, and late-October conditions can swing from warm to cold. For most riders the goal is to finish strong without flatting out of the day.
What makes it hard
- Sharp, chunky gravel. The Ozark rock is notoriously hard on tires — sidewall cuts and flats end Big Sugar days that fitness never would.
- Punchy, repeated climbing. Rather than long passes, the course throws short steep climbs at you again and again, demanding legs that can surge and recover repeatedly.
- Repeatability over a long day. Around 100 miles of constant ups and downs taxes your ability to produce power over and over without blowing up.
- Variable late-October weather. Conditions can range from warm to genuinely cold, and a wet year changes traction and tire choice significantly.
What the day actually demands
Big Sugar is an aerobic endurance event with a strong repeatable-power component. The punchy climbs mean you are constantly accelerating and recovering, so the rider who wins the day is the one who can crest climb after climb without overspending early.
Pace the short steep climbs with discipline. They are tempting to attack because they are over quickly, but doing that a hundred times is how legs disappear at mile 70. Climb them steady, recover on the descents, and keep something in reserve.
How to build toward it
A runway of 12 to 20 weeks suits most riders. Build a solid aerobic base with long rides, then layer in repeated efforts — short, hard climbs with recovery between — to train the punchy repeatability the course demands.
A productive week is one long endurance ride, one session of sweet-spot or threshold work plus some short over-unders or VO2 repeats for the steep pitches, and easy riding around them. Practice the rolling, surging rhythm rather than only steady-state riding.
If you can find chunky, technical gravel to train on, use it — comfort and confidence on rough surfaces saves real energy over a long day.
Fueling and hydration
Even in cooler autumn weather, fueling decides the back half of the day. Practice 60–90 grams of carbohydrate per hour on long rides so your gut is ready, and do not let cooler temperatures trick you into underdrinking.
Plan where you will refuel, carry enough between stops, and rehearse eating on a course that rarely gives you a smooth, easy stretch to do it.
Equipment and tires
Tire choice is the defining equipment decision at Big Sugar. The sharp Ozark rock punishes thin, fast tires, so most finishers run tougher, more protective tubeless tires with adequate volume — trading a little speed for not slicing a sidewall.
Carry a repair kit you can use under pressure — plugs, a spare tube, a reliable way to add air — and practice a roadside fix beforehand. Check the official event site for the current year’s route, distance options, and any course changes.

Common questions
Why do so many riders flat at Big Sugar?
The Ozark gravel is sharp and chunky, which is hard on tires. Many riders reduce their risk by running tougher, higher-volume tubeless tires at a sensible pressure rather than the fastest, thinnest setup. Carry a repair kit and know how to use it.
How hilly is Big Sugar Gravel?
Very — but in short, punchy doses rather than long climbs. Expect a constant series of steep rises that add up to a lot of vertical over the day, so training repeatable climbing power matters more than long sustained climbs.
