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 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 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.

The Remmerswaal Vestingloop in Bergen op Zoom, Brabant, is a road race held in November on paved courses. It caters to a diverse range of participants, offering a 1 km Family Run, a 5 km run, a 10 km run, and a 5 km walking tour. Options for a fun run, training run, and virtual run are also available. The event has a participant limit of 3,500. The course incorporates the historic city center, guiding participants past Bergen op Zoom landmarks like the Lieve Vrouwenpoort and the Peperbus church tower. The 10 km race follows a distinct route, while the shorter distances are designed for accessibility to families, walkers, beginners, and experienced club runners. Organizers describe it as a "hardloopfeest," translating to a running party, reflecting its multiple distances, urban setting, and the inclusion of local historical points of interest, distinguishing it from a simple out-and-back course.

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 Van Rijn 3Plassenloop is on the Go Dare Street running calendar.

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.

The Santa-Run is a 1.60 km fun run in Prinsenbeek, starting from the Markt in the village centre. It is a short Christmas-themed event rather than a competitive distance race, with runners taking part in Santa suits or other festive costumes. The course has music along the way, and the event continues after the run with a get-together in the ice rink on the Market. Overbosloop organizes it, public transport access is available, and a first aid post is present at the event.

The Mundo Nieuwjaarsloop begins the running year in Oud-Beijerland, South Holland, starting at AV Spirit on Langeweg 14.

The course is certified, making the 10 km suitable for those seeking an officially measured distance or simply wanting to be active after New Year's. AV Spirit organizes this race, now in its third decade. The event accommodates beginners, experienced athletes, walkers, club runners, and faster 10 km participants, with a request to keep right for safe overtaking. Entry provides a start number and medal; the 10 km includes rankings and online results, with water and AA Drink available. Participants can also choose to donate to De Voedselbank Hoeksche Waard, the local food bank.
