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. Portions of the course overlook Charleroi, providing more variety than a typical city road race. The event accommodates both adults and children. 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.

Corrida de Jodoigne is an October night road race held in Jodoigne, Walloon Brabant, Belgium. It crosses the town's historic center and features two primary distances: 5 km and 10 km. A 1.4 km children's run is also available for participants aged 6 to 12. The course has the organizer as surprising and somewhat technical, deviating from a simple flat run through town streets. The event accommodates various participants, from those aiming for a specific time to families and runners seeking a shorter evening race. Each distance has a participant limit of 500.

La Gelbressoise is a small nature-running event in Gelbressée, near Namur in Belgium’s Ardennes region, held in November. Participants can select from 20 km, 12 km, and 5 km courses, accommodating those seeking a longer countryside run and those preferring a short local race. The three distances are managed as distinct events, with limits of 300 runners for the 20 km and 600 runners each for the 12 km and 5 km. Registration is exclusively online, without on-site sign-ups. The stated fees are 10 EUR for 20 km, 7 EUR for 12 km, and 5 EUR for 5 km, prior to additional registration charges.

Foulées Hivernales ART is a winter forest run in Watermael-Boitsfort, Belgium, starting at Collège Saint-Hubert. Participants can select either a 5 km or 12 km distance, both beginning in the morning. The event has a limit of 1,000 participants. Registration must be completed in advance; no race-day sign-ups are permitted. Each runner is assigned a time slot to collect their bib. The course is contained entirely within the Sonian Forest, presenting a compact trail-style event distinct from city road races. The return to the finish line retraces the initial path. A drink station is available on the 12 km course within the forest. ART Running Team organizes this event, part of its Foulées race series which includes a summer edition. The event also supports the Belgian Cardiology League.

On Ciney's hilly streets, fewer than a handful of runners have ever broken 30 minutes for the 10 km since 1988. The Corrida de Ciney is a late-December road race in Ciney, Belgium, in Namur province and the Condroz region. Runners can choose 5 km or 10 km, with children's races also on the program. The race is also called the Corrida des Féeries or Corrida de la Saint-Sylvestre, fitting its slot between the end-of-year holidays. The course runs through the city rather than on a flat, purpose-built speed loop, so fast times stand out. The event is organized by ARCH Athlétisme and draws a large local field, with recent participation around 1,500 finishers and earlier editions already topping 1,100 athletes. It also includes a Think Pink team relay and joëlette races, so the day is not only for club runners chasing sharp times. The front end can still be serious: the 5 km has produced course-record running, close duels between local and regional athletes, and winners with track credentials such as steeplechase specialist Clément Labar.

Jogging de l'Athénée de Gembloux is an evening street race held in Gembloux, organized by the Athénée Royal de Gembloux. Adult participants begin at 19:00 and can select between a 5 km or 10 km distance. The 10 km route involves completing the 5 km loop twice. This race is designed for a wide range of participants, not exclusively fast club runners, featuring an accessible urban course, aid stations, professional timing, and changing facilities. The school's involvement is integral to the event. Children under 12 can participate in a free kids' run at 18:30, and childcare is provided during the adult races. Students and school staff benefit from a reduced entry fee, with affordable options available for external runners. Following the races, a bar and refreshments are available, making the event a community gathering for the local school and residents, in addition to being a 5 km or 10 km race.
