About the Legends Backyard Belgium

Legends Backyard Belgium brings an international field to Domein Beverdonk for one 6.706 km yard every hour until a single runner completes the final loop. The race has become one of the format's strongest performance stages, with deep fields and repeated 100-yard results.

The Retie venue is designed for long attempts rather than novelty mileage. Runners return to the same support base each hour, while the day and night course change keeps footing predictable as the field moves through multiple sleep cycles.

Course

The 6.706 km daytime yard mixes gravel roads, tarmac and wooded sections. From evening through early morning, runners switch to a faster out-and-back on gravel roads and tarmac before returning to the day loop.

Race-day weather

Late April in northern Belgium is often cool and changeable. Rain can soften wooded sections, while clear nights may feel markedly colder than the afternoon.
