La Course du Bois du Cazier begins at the Bois du Cazier in Charleroi, a UNESCO World Heritage site in Hainaut, Belgium.

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.

The STYREKX Fitness Race Mechelen is an indoor fitness competition in Mechelen, Antwerp province, Belgium, taking place in October. It combines short running circuits with functional exercise stations, resembling a timed gym challenge more than a typical road race. The primary Regular and Xtreme formats consist of ten 800-meter laps, totaling 8 km of running, with an exercise station following each lap. A shorter Light option features nine 400-meter runs. The event is part of the Strong Viking series and maintains an arena atmosphere, incorporating chip timing, designated stations, and a consistent run-exercise cadence. The course is constructed from repeating laps and gym-based exercises, distinct from outdoor obstacles or terrain. Stations involve equipment or activities such as RowErg, StrengthErg, Sled Push, and Loa, with exercises drawn from standard fitness and CrossFit routines. Participants can compete individually, in pairs, or as teams, and the organizer states prior fitness race experience is not required. Staff are stationed to guide participants through the exercises, and the timing chip tracks running, station completion, and transitions. Entry includes a STYREKX Patch, and finishers receive nutrition, a personalized results breakdown, and a certificate; facilities like changing rooms, a cloakroom, and a hydration station are also provided.

The Relais des Feuilles Mortes is a 5 km road race held in Honnelles, Belgium, starting in Montignies-sur-Roc. It takes place in late October. Walkers begin at 14:30, followed by joggers at 15:00, making it a brief autumn run rather than a full race day. The available information suggests a modest local event: a single 5 km race, a distinct walking category, and Laurent Gallez as the race director. The name translates to "relay of dead leaves," appropriate for the late-season timing. The race is relatively new, having only a few editions completed.

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.

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.

RRunning Cousolre organizes the event, fostering a local and welcoming atmosphere where night-trail regulars and newcomers share the course. Post-race, participants receive homemade soup and substantial refreshments, aligning with the event's straightforward concept: compete intensely in the dark, then recuperate together.
