La Course du Bois du Cazier begins at the Bois du Cazier in Charleroi, a UNESCO World Heritage site in Hainaut, Belgium. This event offers mixed road and trail running, with adult races around 6 km and 16 km, and children's runs of 500 meters and 1 km. The shorter adult course is just over 6 km, and the longer one is a little over 16 km, meaning the listed distances are approximate. The route departs the historic mining site, passing through Marcinelle via paved sections, slag heaps (terrils), and forest paths.

Adult participants receive a bib, electronic timing, aid stations on the course and at the finish, a medal, and a raffle entry. Children get a bib, a snack at the finish, and a medal.

Vestingloop Bergen op Zoom begins and ends on the Grote Markt, located in the historic center of Bergen op Zoom in North Brabant. This road-running event offers short, accessible distances: a 1 km family run, a 5 km run, a 10 km run, and a 5 km Ommetje walking route. The schedule also features 5 km and 10 km corporate runs, welcoming not only club runners focused on speed but also families, walkers, colleagues, and casual runners to the same event. The course highlights the fortress-town's character instead of obscuring it. Participants will run past city landmarks including the Markiezenhof, the Ravelijn, the Lieve Vrouwenpoort, and the Peperbus. The Grote Markt serves as the central gathering point before and after the race. The event benefits the Hersenstichting, the Dutch Brain Foundation, adding a fundraising objective to the running and walking activities. Its core concept is a concise city run through historic Bergen op Zoom, with distances suitable for both novices and experienced runners.

Relais de Vauban is a 16 km team relay in Maubeuge, a town in northern France near the Belgian border. The race runs in the city centre around Vauban’s historic ramparts, and it is built around a simple format: three runners each cover a 4 km lap, then the team runs the final 4 km together. It has usually been held around the autumn holiday period, with a move toward October for the next edition. The course is a short city circuit rather than a point-to-point route, so teams return to the same area as the relay changes hands. Its setting gives runners old fortifications, urban streets, and green spaces in one compact loop. Maubeuge Marathon organizes the event, with aid stations and changing rooms on site. The field is aimed at mixed local teams, club runners, casual runners, and people who want a shared race rather than a solo effort.

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.

This is a modest urban running event featuring 10 km and 6 km races, with a walking start at 09:30 and the main running start at 10:00. The course follows town roads, not trails, and the event includes canicross options over the same primary distances.

The Velpe Mene Trail begins and ends at Sportcentrum Houtemveld in Tienen, leading participants into the natural areas surrounding Tienen and Glabbeek. This late-November trail race offers three distances: 10 km, 19 km, and 29 km. Natuurpunt Velp-Mene, the local nature organization responsible for managing several reserves in the region, organizes the event. Consequently, the race focuses on running through protected natural areas, avoiding roads and urban streets. The courses are predominantly off-road, with approximately 75% unpaved for the 10 km and over 80% unpaved for the longer distances. Each distance features a unique route, though some sections overlap. Portions of the course traverse private property or deviate from standard walking trails, granting runners access to normally restricted areas. The 10 km route is suitable for all ages and serves as an introduction for novice trail runners. The 19 km and 29 km routes are restricted to participants over 16 years old, catering to those seeking an extended, relaxed outing in nature. Registration is limited to 525 participants, and participation fees contribute to local nature conservation efforts.

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.
