The course is marked according to GR standards, with a GPX file provided the week prior as a supplementary guide.

The Brandweer TRAIL begins and ends at the Zottegem fire station on Meengracht in Belgium. This local trail run, organized by the Zottegem fire station, offers distances of 5 km, 12 km, or 25 km. The event takes place in autumn, with a start window open through the morning, allowing participants to set off between 8:30 AM and noon rather than a single fixed start time. The routes follow the slow lanes, paths, and rural roads surrounding Zottegem, keeping the race contained near the fire station. The entry fee covers course refreshments and a goodie bag, contributing to the event's straightforward community-race atmosphere. Its distinctive feature is the fire-station start and finish, where runners begin and conclude at the active base of the organizers.

Donkmeerloop De Mooiste Halve is a road race held at Festival Hall Donkmeer in Berlare, East Flanders. The start and finish are on Donklaan, adjacent to the lake. The race offers 6 km, 12 km, and half marathon distances, and is scheduled for autumn. Jente Samson, the Flanders Project Team, the municipality of Berlare, and the Province of East Flanders organize the event. It has been held for 11 consecutive editions, expanding from 450 participants in its first year to over 2,000, with fields now sold out. The courses traverse the Donkmeer area, the old duck decoy, and Nieuwdonk. This ensures even the shorter distances offer the same lake-and-park environment as the half marathon. Half marathon participants can utilize seven pacers, identifiable by orange shirts, aiming for finish times between 1:20 and 2:10. Past editions featured the Belgian Championship, charity runs, and support for a children's heart fund.

The Aartsen 10 km is the 10-kilometre race held as part of the Arrow Venloop in Venlo. It takes place alongside the Van der Valk Hotel Venlo Half Marathon, meaning the event is structured around both a 10K and a half marathon, not a single main distance. The most notable aspect is the demand: the 10K sold out over five weeks before race day, and the half marathon also sold out. The Venloop Foundation describes a citywide atmosphere surrounding the race, with runners, walkers, and spectators participating in the same event. The Arrow Venloop is now in its nineteenth edition.

Meerdaalwoud Trail starts and finishes at CultuurCentrum De Borre in Bierbeek, Belgium, then sends runners into the Meerdaalwoud forest area around town. It is a December trail-running weekend, billed by the organizers as the last trail of the year. The menu is broad for one event: short forest runs sit beside longer trail options, with distances listed from about 11 km up to 50 km depending on the day. Saturday usually carries the heavier program, including 13 km, 18 km, 27 km, 34 km, and 50 km races, while Sunday offers shorter-to-mid-distance choices such as 11 km, 19 km, and 28 km. Other listings show routes from 10 km to 43 km, with the 43 km course carrying 582 m of climbing, so runners should expect rolling forest terrain rather than a flat road-style effort. Entry pricing starts at the lower end for the short races and rises for the ultra-distance option, with reduced rates tied to Ultra Trail membership.

Les Hivernales du RCB is a timed winter running race in Watermael-Boitsfort, located in the south-eastern part of Brussels. It features three course options of approximately 10, 20, and 39 kilometers. The start and finish points are typically situated at the International School of Brussels. The race route incorporates sections of the Soignes Forest, utilizing unpaved paths, making it a forest road-and-trail event rather than a flat city race. The shortest race is advertised as 10 km, though its actual length may be closer to 9.2 km. Race organizers note that official distances are subject to change. The initial kilometers are relatively flat before the course presents challenges: a sustained climb of about 1.2 km at a 5% gradient, followed by an 800-meter descent, additional smaller ascents, and a final 400-meter uphill stretch preceding a downhill finish. Both licensed and non-licensed participants are permitted. The event's guidelines are straightforward: adhere to course markings, show consideration for fellow runners, and confine litter to designated aid-station zones.
