TRAIL BRUSSELS – 29.10.2017

The Sonian Forest is a treasure trove of rare biotopes and typical types of forest. To protect them all, the most valuable parts of the forest have been designated forest or nature reserves. The second edition of Trail Brussels will take place on Sunday, October 29. Runners can choose between 4 different courses through the green lung of Brussels, the Sonian Forest: 6, 13, 21 and 28km, all with the necessary altimeters.

10. Charity


The number of homeless people in Belgium increased the last 15 years by almost 200%, from 17,000 in 2003 to 50,000 in 2015. While there are a lot of statistics available, it is mainly guesswork about the exact amount of people living on the streets. Therefore it is important that organizations get support, because after all, they are in direct contact with the homeless. Everybody has the right to get shelter!

Let us together create a better world for the homeless!
For every euro you donate, we will add one more!



11. Qualifying race Ultra-Trail du Mont-Blanc®


From 1 January 2016 the Ultra-Trail du Mont-Blanc® uses a new points system for qualifying races to participate in the UTMB®, CCC® & TDS® and the OCC. These points are obtained by the formula: distance (km) + (altimeters (m) / 100). For example: A race of 55km and 2200m+ will give you 55 + (2100/100) = 76 points which result in 3 qualification points.

Here you can see the necessary number of points for the current edition. The application procedure requires a run GPX file, which we have to upload on tracedetrail. If our race is not yet among the official qualifying races on the UTMB website, this means that we still have to submit a GPX of our race to complete our request. The number of points that we show on our website is always correct and we 100% guarantee this.

Start and finish are located at the BLOSO sports center Forêt de Soignes Sport.

Below you can click through to the interactive course maps, indicating the locations of the aid stations and river crossings. There, you can also download the GPX files (To do this, you first need to create an account on tracedetrail)
