Grelly '25 is a self-supported bikepacking event = NO external support allowed! Riders may only use services accessible to everyone (shops, hotels, restaurants, local bike shops, …) or accept friendly, unsolicited help from passersby.
​
The track of your choice will be shared one week before the event. This track must be followed and completed within the prescribed time limit. 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 45mm tires (or more) and small gearing or a mountainbike: Comfort is more important than pure speed. NO electric bikes are allowed. Of course: No motor, no public transport - just you, your legs and your bike
The registration fee is 150 € per rider to cover all the costs.
This fee includes:
- Use of a GPS-tracker (no deposit required this year; we trust you to return it at the end of the event),
- Free breakfast before the start for both 3 and 4 days adventure,

Important !
​​
GRELLY Adventure is NOT a race - you are fully responsible for your own safety at all times ! Stay visible, especially at night, and wear a helmet at all times! Your progress will be monitored and published via a tracking system (so your friends, family, and fans can follow you), but no official ranking will be made.
​
Drafting is only allowed for 'Duo'-teams. Spontaneous/social riding, resting and camping in groups are, of course, permitted.
​
No deposit is required this year for the GPS tracker. However, please note that you are responsible for the tracker, and in case of loss or damage, we will kindly ask you to cover its cost (€150). We count on your honesty !
​

Cancellations after June 1st will not receive a refund.
The maximum number of participants is 125 (excluding female riders), the minimum is 25.
​
