⏵ Course guide · Lincoln, Nebraska
The Lauf Gravel Worlds Run Series sends the 50K, half marathon, and 10K rolling across what the race calls the Nebraska gravel seas, a self-supported weekend sharing its dates with the well-known Gravel Worlds bike race in Lincoln. I will walk you through the course and format first, then give you a pacing and fueling plan built for a self-supported gravel ultra. There are free calculators along the way to dial in your own numbers.
These facts come from the official race site. Check the current year details before you commit. Race logistics can change year to year.
The run series shares its route character with the famous Gravel Worlds bike race: rolling gravel roads, open sky, and a genuinely self-supported feel.
The race describes the course as navigating "the Nebraska gravel seas," out of the Sandhills Global Event Center in Lincoln, with the final mile on trail. Expect long, rolling stretches of gravel road rather than singletrack, a wide-open, exposed kind of terrain that rewards steady effort over technical skill.
The race is explicit that this is a self-supported event, even with aid stations staffed by the Gravel Worlds crew along the way. That distinction matters for a 50K: plan to carry more of your own nutrition and fluid between stops than you would at a heavily aid-stationed road ultra.
The run series shares its August weekend with the well-known Gravel Worlds bike race, so expect a genuine gravel-community atmosphere around the event, not just a standalone trail run. If you like the energy of a bigger weekend built around one shared course philosophy, this is a distinctive way to get it on foot.
With a 5:30 AM start for the 50K, plan for a cool opening hour and rolling terrain that never sustains one long climb or descent for long.
Rolling gravel roads rarely let you settle into one number for long: short climbs and descents string together across the course. Aim for a steady, sustainable effort rather than chasing a single per-mile pace, and expect your splits to vary more than they would on flat pavement.
Because the event is self-supported even with organizer-staffed aid stations, treat the gaps between stations as genuine self-sufficiency stretches. Carry enough fluid and calories to comfortably bridge each segment rather than assuming frequent top-offs.
⏵ Free tools to plan your effort
Self-supported does not mean unsupported, but it does mean you should plan your own numbers rather than counting on constant aid.
Aim for roughly 40 to 70 grams of carbohydrate per hour for the 50K, adjusted down for the shorter half marathon and 10K if you are racing them hard. Bring what you need to comfortably cover the gaps between the Gravel Worlds crew's aid stations rather than relying on them as your only source.
The 5:30 AM 50K start gives you a cool opening stretch, but rolling gravel roads with little cover can heat up fast as a late-August Nebraska day goes on. Plan sodium in the 400 to 700 mg per liter range and adjust your fluid intake upward once the sun is fully up.

The 50K, half marathon, and 10K all run on rolling gravel roads the race calls "the Nebraska gravel seas," out of the Sandhills Global Event Center in Lincoln, with the final mile on trail. It is a fully self-supported event, with aid stations provided by the Gravel Worlds crew rather than a dense, road-marathon style aid network, so this rewards runners comfortable managing their own nutrition between stops.
The run series shares its weekend with the well-known Gravel Worlds bike race, one of the sport's notable long-distance gravel events, giving the run weekend the same Nebraska gravel-road terrain and organizational team. It is a genuinely fun atmosphere if you enjoy being part of a bigger gravel-cycling weekend rather than a standalone running-only event.
The official race page I checked does not publish specific cutoff times for the 50K, half marathon, or 10K. Confirm the current year's cutoffs on the official race page or with the organizers before you commit to a goal pace.
Gravel roads are non-technical compared to singletrack, but "self-supported" is the operative phrase here: with aid stations provided but the event not run like a dense road ultra, you need to manage your own nutrition and hydration between stops on rolling terrain over 31 miles. Treat it as a genuine ultra effort on a runnable surface, not a road 50K with gravel underfoot.
The non-technical rolling-gravel surface is about as forgiving a first-ultra terrain as you will find, no roots, rocks, or route-finding to worry about. The self-supported format is the one thing to prepare for specifically: practice carrying and managing your own fuel and fluids between aid stations before race day, rather than assuming support will be as frequent as a fully crewed road race.
It is a non-competitive 5K held Saturday, August 22 at 5:30 PM, the evening before the main Sunday distances. It is a relaxed way to shake out your legs and be part of the weekend if your main event is the 50K, half marathon, or 10K the next morning.
