Can you run, hike or ride in a storm, wind or snow? How to read Belgium's weather warning colours

Code yellow, orange or red: what does it mean for your run, hike or ride? Here are the thresholds Belgium's Royal Meteorological Institute (RMI) uses for wind, rain, thunderstorms, snow and fog, why the forest is the most dangerous place in a storm, how to decide on the day, and when to turn back or call 112.

What is a backyard ultra? Rules, records and the 2026 World Team Championship explained

In a backyard ultra you start the same 6.7056 km loop every hour until only one runner is left. Here is how the rules work, how the record moved from Belgium to Australia and Poland and past 120 loops, how the World Team Championship works, what happened in Retie in October 2026, and how to run your first loops on the hour.

What is gravel running, and do you need special shoes for it?

Gravel running is running on forest tracks, gravel paths and country lanes: an accessible in-between step between road and trail. What the name means, how it differs from road running and trail, what gravel shoes do differently, whether you really need them and how to run a first loop in Belgium.

Can you follow a path just because it's on the map? What route data does and doesn't tell you

A path on your map or in your app isn't permission to follow it. Here's how to read map lines, hunting notices in Wallonia, GIPOD notices in Flanders and climbing figures on route pages, and how to turn them into a short, useful check before you leave.

Can you hike or run in a Walloon forest in autumn when hunting is going on?

Yes, on the roads and paths open to the public, unless a closure or sign on the spot says otherwise. Here is how to check announced hunting days in advance, read the signs on the day itself and know when it is better to turn back.
