Harbour Run Rotterdam guides participants through the working port of Rotterdam, featuring obstacles such as climbing over large containers. This annual obstacle run in Rotterdam, Zuid-Holland, Netherlands, typically takes place in October, offering 6 km and 10 km distances instead of a conventional road-race format. The course navigates Rotterdam's port areas, presenting an industrial landscape rather than parkland or city streets. SportVibes organizes the event, collaborating with obstacle, course, and business partners, as well as the Port of Rotterdam, with their partnership extending to 2028. Companies can register business teams for colleagues to compete together, and the event also benefits Ronald McDonald Huis Sophia Rotterdam.

The Janlouterloop begins at AV Fortuna on Watersportweg in Vlaardingen, leading runners into the Vlaardingse Broekpolder during autumn. Organized by AV Fortuna and affiliated with the Atletiekunie, the race offers 5, 10, or 15 kilometer distances. Starts are scheduled in late-morning waves, with entry fees varying by distance. The race commemorates Jan Louter, a former AV Fortuna trainer and dedicated runner who passed away from pancreatic cancer. He coached multiple running groups at the club, logged extensive mileage, and was known for his motivating enthusiasm. Net proceeds benefit Support Casper, a program of the Dutch Foundation Survive Pancreatic Cancer.

The Dordtse Biesbosch Trailrun begins and ends at the organizer's grounds on Schenkeldijk in Dordrecht, South Holland. This trail race crosses the Nieuwe Dordtse Biesbosch, offering distance options from short Family Runs to a half marathon. Participants can select 3 km or 5 km Family Run courses, a standard 5 km, 10 km, 10 English Miles, or a 21.1 km half marathon, catering to children, novice runners, and those seeking a longer off-road challenge. The courses feature narrow paved paths, unpaved tracks, sandy stretches, and dikes, leading through the Nieuwe Dordtse Biesbosch, the floodplains beside the Nieuwe Merwede, and the Elzenbos. The trail surface may present puddles, streams, branches, and tree trunks, making the race a test of adaptability to varied terrain rather than a pursuit of speed on a smooth road. The start-finish area provides baggage drop-off and changing facilities. The event maintains a relaxed outdoor atmosphere with campfires, marshmallow roasting for children post-race, and refreshments including coffee, tea, soft drinks, satay, and beer.

The GOUDasfaltloop is a small running event in Gouda with a cap of 150 participants and distances from 240 meters up to 10 km. It includes short youth races under the KidsRun banner, plus 5 km and 10 km options for adults or older runners, and the Pacer element gives runners a way to aim for a steadier target pace. Entry fees are low, from €5 to €13, and late registration is allowed when places are still available. The route goes through the Veerstalblok polder and over the Tiendwegen, with the start, passing points, and finish tied to the GOUDasfalt event grounds. That setup keeps the race compact: runners head out into open polder roads and return to the same event site. Earlier editions also included a photo contest and small surprise elements, so the day is pitched more as a local community race than a large city run.

The Zorg en Zekerheid Circuit is a paved road running series held in Leiden, South Holland. Participants can register for the entire circuit rather than individual race days, with 5 km, 10 km, and 15 km distances available. The process is simple: circuit participants collect their bibs at the information desk on race day, where same-day registration is also managed. The entry form lists short, middle, and long distance categories, along with a short-distance option for ages 12-18. Runners aged 15 and under require parental or guardian consent.

Vestingstad Run Woudrichem is a paved running event starting at Atletiekpark Altena in Sleeuwijk. The half marathon route extends into the historic fortress town of Woudrichem.

All distances follow a single loop on roads with controlled traffic through the countryside surrounding Altena, Woudrichem, and Sleeuwijk.

Pre-registration is mandatory, with a limit of 500 participants. Previous editions have featured close competition, such as a course record being improved by only two seconds in wet weather.

Urban Trail Haarlem is a run through the center of Haarlem, with a route designed to showcase the city from both its interior spaces and its streets. It is part of the Dutch Urban Trail Series, which takes runners into notable Dutch cities for a sporty city-discovery run instead of a standard road race. The Haarlem event is limited to 3,000 participants and is now in its sixth edition. The course connects running with culture and architecture, focusing less on achieving a fast time and more on moving through Haarlem’s inner city via locations a normal race would not typically access. The start is at Oudeweg 91-95, and the event offers practical race-day amenities such as public-transport access, first aid, a guarded cloakroom, and late registration if spots remain.

The KPN Halve Marathon Gouda takes place in Gouda on the second Sunday of November, starting on the Markt in the historic city centre. The event offers adults a half marathon or a 10 km race, and children's races for younger runners, catering to multiple distances. The precise routes will be disclosed by the organizers nearer the event. This race is designed as a local mass participation event rather than a large-scale city marathon, with a limit of 3,500 participants. Recent events have seen over two thousand runners, and late entries are not permitted, so participants must register by the standard deadline.

The Night Trail Run Utrecht begins and ends at Skipiste Nieuwegein, south of Utrecht. Participants start after dark on a Friday evening in November. BodyRun and IJ-Run are the organizers. The event features 15 km and 7.5 km trail runs on unlit paths. Paved course options are also available for those who prefer the night atmosphere without the challenging off-road terrain. Participants must provide their own lighting; headlamps are required for the trail distances. The trail courses include undulating sections and short, steep climbs, adding difficulty beyond the darkness. A 5 km Fun Run follows a paved figure-eight path around the Nedereindseplas, suitable for beginners or families who can complete it within an hour. A mostly flat, paved 10 km run in the dark is also offered. Trail race participants must be at least 12 years old. First aid and a mixed changing room are available. The event concludes with an after-party at Skipiste Nieuwegein, running until midnight. Donations are collected for Stichting Veer(le)kracht.

The Hollands Duin Trail begins at Vrijstaat Nederzandt in Noordwijk, on the Dutch coast. Routes are set within the protected Hollands Duin nature reserve. This trail running event offers four distance options: 6 km, 10 km, 21 km, and 30 km. The shortest route includes 15 meters of elevation gain, and the longest route has 100 meters. The challenge stems more from sand, turns, and narrow paths than from significant climbs. The course guides runners through Noordwijk's dune area, onto the beach, and along forest paths featuring ample single track. All routes are marked, and aid stations are situated at fixed locations. Trail Events organizes the race, now in its fourth edition. The primary appeal is the location: runners navigate between coastal dunes, open sand, and woods, all within the Noordwijk area.

The AVA Zorg en Zekerheid Westeinderloop is a road race in Kudelstaart, Netherlands, beginning at Wim Kan Dreef 4. It takes place on a Sunday in late November and offers runners multiple options: a kids run, a G-run, 5 km, 10 km, and a 10 English mile race covering 16.1 km. AV Aalsmeer organizes the event, which is affiliated with the Atletiekunie, the Dutch athletics federation. The participant limit is 2,000, making it a local club race suitable for families, recreational runners, and those attempting the 10-mile distance. The arrangements are functional, including late registration, changing rooms, showers, massages, a guarded cloakroom, parking, first aid, and AEDs available on-site.

The Sint Nicolaasloop is a late-autumn running event in Zwolle, Overijssel, held on the Saturday before Saint Nicholas' birthday. It is built around several distances rather than one headline race, with options such as a kids' run of about 1.5 km, shorter runs around 5 to 6 km, an 8 km race, and a 10 English mile route of about 16.1 km. The runs use the rural area north of Zwolle, starting from Sportpark de Pelikaan in recent editions and sending runners out into the open countryside outside the city. The Saint Nicholas theme is part of the day, with Sinterklaas and his helpers appearing at the event. The race started in the seventies, when Skivereniging Zwolle used it as winter-sport preparation for its members, so its roots are more local club training than big-city spectacle.
