Max 50 participants. We do not limit the amount of female riders! We will keep a small waiting list.

GG 100 is a self-supported bikepacking event = NO outside assistance! We only allow support available for every rider (shops, hotels, restaurants, local bike shop, …) or friendly offered by a coincidental passenger.

A track will be provided 1 week in advance. This track must be followed and completed within 100 hours. When, at some point during the challenge, you leave the track, you must rejoin the track at the very same point to continue.

Recommended bikes: a gravel bike with at least 40mm tires and small gearing or  a mountainbike. NO electric bikes are allowed. Of course: No motor, no public transport - just you, your legs and your bike


The registration fee is 70€ per rider to cover all the costs. This fee includes:

- Use of a GPS-tracker (100€ deposit, reimbursed when returning the tracker),

- Free pasta and one drink at the start,

- Free drink at the finish,

- Goodie bag (with the support of our Partners),

- A rider's guide with useful and detailed information,

- Bike wash, 

- Shower at the finish,

- Chill atmosphere at the start & finish. We will broadcast the UCI Road World Championships at the finish !

- ...  

Important !

The GG 100 is NOT a race - you are responsible for your own safety at all time ! Via a tracking device your actual progress will be monitored and published (so your home front, fans, friends ... can follow you) but no official ranking will be made. Follow the traffic rules at any time, be visible especially at night, wear a helmet all time !

Drafting only for 'Duo'-teams. Spontaneous/social riding, resting and camping in groups is of course allowed. 

In addition to the registration fee, you’ll need to pay a deposit of 100€ for the use of the tracker. This amount will be refunded after returning your tracker at the finish or sending it by post (in case you did not make it to the finish).

If a participant cancels his registration before August 1st 2021, he/she will receive a 50% refund. 

If the cancelation is done after 1st of august, the participant will receive no refund.


The maximum number of participants is 50 (with exception of female riders), the minimum is 10.

At all-time the organization can decide (e.g. due to governmental restrictions) to cancel the event. In that case the organization will decide if the participants that already paid, will get a full refund or will be automatically registered for the next edition.

Mandatory documents to show us at the start of the course are:

*) your Insurance Certificate, from your liability insurance
*) a recent Medical Certificate, confirming your ability to practice long-distance endurance cycling, provided by your doctor. This can be as well a valid cycling license.
