Remaining race numbers can be collected on race day, in the time slots given to you according to the distance of your race. See Program

To collect your race number:

• Identity card or copy of identity card
• Medical certificate in order for GT160 and GT85. If no certificate = no start!
• Each participant must present himself with his compulsory equipment, and agree to keep it with him for the duration of the race (see regulations on our website).

Access to the site:

Please respect your time slots.

There will be no lockers for your keys or valuables.

What will I receive when I collect my number?

• Your number
• Your wristbands if you are in the GT85 and GT160 distances
• Your GPS beacon: GT160 / GT85
• Colored bracelets to label your drop bag (= personal bag for GT160 / GT85)

Display of race number :
The race number must be worn on the chest or stomach and be permanently and completely visible throughout the race. It must always be worn on all clothing and may under no circumstances be placed on a leg or bag.

Maximum capacity of 30l per bag. Please provide a bag where you can hang the colored bracelet on your bag, which you will have carefully prepared before departure and which will be delivered by our team to the right place.

GT85: 1 coloured wristband (R2: 40km)

You'll need to drop them off yourself at the coloured points on race day. They will be placed by the organization at the refreshment points described in the roadbooks (see GT page for each race).

Refreshments will be provided at the points described in the road book:

The principle of an individual race in semi-autonomy is the rule. Semi-autonomy is defined as the ability to be self-sufficient between 2 refreshment posts, in terms of food, clothing and safety, and to adapt to any problems encountered or anticipated (weather, physical problems, injuries, etc.). It's also why we got those UTMB Index points, and why the GT160 is also a qualifier for the Western States draw.

Refreshment points are accessible to participants only.

You must have your own personal cup!
A detailed table will be sent to you by e-mail.

Having the GPX route loaded on your watch/smartphone is a MUST for the GT85. The routes will be 100% signposted BUT, unfortunately, signposting is becoming increasingly frequent and is beyond our control. External batteries are therefore recommended for smartphone use! Each runner is warned and is responsible for the way he/she works in case of problems.

GPX tracks for the GT160 | GT85 | GT42 | GT21 | GT11 will be e-mailed individually to registrants 2 days before the race.

These routes take in many private passages that are not accessible outside the trail.
We have the trust of the owners. Don't break it by using them outside the GTLC weekend.

All along the route, you'll follow white arrows with orange tips. All have reflective tabs. In the non-wooded sections, orange ground markings point the way.

Example of a fork sign and a sign to certify that you are on the right road after a fork: See Roadbook

For 2 distances: GT160 / GT85, for safety reasons, you will receive a beacon at the start, to be attached to your race bag and returned at the finish.

This GPS chip will be given to you when you pick up your number (compulsory).
This beacon is used by our Race HQ team for your safety.

Just for you : POP UP!!!

From Saturday 4h00, a "pop up" will be available on our website www.grandtrail.be.

Signallers and traffic regulations

Even if we have a great team of volunteers as signallers, each participant will have to comply with the highway code. Road crossings are made under the full responsibility of the runners, with renunciation of any recourse against the organizers in the event of damage or after-effects which could occur during your race. When you registered, you ticked the little box that says you have read and accepted the regulations on our website.

Barriers are calculated according to your own departure times.
