🔥 Have you ever wondered how far you could ride in 40 hours?
On 17-18 October 2026, we are organising a 600 km Brevet.
About the Event
A
brevet
is an international long-distance cycling challenge
with over a century of history.
It is an opportunity to test your endurance,
time management and planning skills.
You are not competing against others.
You are challenging your own limits.
Simply put, to successfully complete the brevet,
you must finish the designated route within
the 40-hour time limit.
- Distance: 600 km
- Time limit: 40 hours 00 minutes
- Format: Self-supported
Self-supported means that participants are responsible for their own navigation, food, hydration, rest and mechanical issues. Outside assistance is not permitted beyond checkpoints, except for services that are publicly available to everyone.
About the Route
The route starts and finishes in Tbilisi, at Maghlivi Bridge. After the start, riders will head towards the Kakheti region, passing through Pankisi Valley, Kvareli, Heretiskari and Samtatskaro. The route combines long stretches across the Alazani Valley, the diverse landscapes of eastern Georgia and scenic mountain roads. During the final stage, participants will cross Gombori Pass before returning to Tbilisi.
The total route distance is approximately 606 kilometres. It includes fast and relatively flat sections, long climbs and challenging descents. The route is predominantly paved.
The main challenges are the overall distance and the significant amount of climbing. Participants will need to manage their energy, pace and rest carefully over almost two days of riding. Gombori Pass, located in the final part of the route, may prove particularly demanding, as riders will already be experiencing considerable fatigue.
Participants will ride during both daylight and nighttime hours. In October, temperatures can vary significantly between the lowlands of Kakheti and the mountainous sections of the route. Riders should be prepared for cold nights, fog, rain, strong winds and reduced visibility.

Important note: According to the current ACP regulations, the opening and closing times of intermediate checkpoints are indicative and help participants assess whether they are on schedule to complete the brevet within the overall time limit. The final and mandatory time requirement is the finish closing time. Participants must also provide proof of passage through every checkpoint.
Who Can Participate?
The event is open to physically prepared cyclists with experience in ultra-distance riding, hilly and mountainous routes, and safe cycling during both daylight and nighttime hours.
A 600 km brevet is not recommended as a first ultra-distance cycling event. Ideally, participants should have previously completed 200, 300 or 400 km brevets, or other long-distance rides of comparable difficulty.
Due to the long climbs and the 40-hour challenge, participants must be able to manage their pace, energy, nutrition, hydration and sleep effectively. Success at this distance requires not only physical preparation but also a realistic understanding of personal limits and the ability to maintain a sustainable riding pace.
Road, Endurance or Gravel bikes are recommended, provided they are mechanically sound and comfortable for prolonged riding. Wider, durable tyres are advisable, particularly considering some of the more demanding sections of the route.
Why Take Part?
A 600 km brevet is much more than just a cycling distance. It is a serious test of determination, discipline, mental strength, endurance and time management.
Riding 606 kilometres through the diverse landscapes of Kakheti gives participants the opportunity to test their abilities across different terrain and weather conditions, learn to manage fatigue and sleep, and gain valuable experience for even longer randonneuring challenges.
The 600 km brevet holds a special place in the randonneuring calendar. Riders who successfully complete a full series of 200, 300, 400 and 600 km brevets within a single qualifying season may earn the prestigious Super Randonneur title.
Completing 600 kilometres within 40 hours requires careful planning, patience and intelligent management of physical and mental resources. Reaching the finish line is not simply about covering the distance. It is about discovering what you are truly capable of achieving.
Recommendations
- Download and save the route to your GPS device or smartphone before the event. Do not rely solely on an internet connection or online navigation.
- Carry a fully charged phone and a power bank with sufficient capacity. Plan the power requirements of all electronic devices for the entire 40-hour event.
- Make sure you have reliable front and rear lights. Spare lights, additional batteries or an alternative power source are strongly recommended.
- Wear a reflective vest or other reflective equipment, especially when riding at night.
- Carry sufficient water, electrolytes and easily accessible energy-rich foods such as gels, energy bars, bananas and other products you have already tested during training.
- Plan where you can refill your food and water supplies in advance. Shops and other services may be limited or closed in remote sections of the route, particularly at night.
- Avoid trying unfamiliar food, drinks or supplements during the event.
- Check your tyres, brakes, chain, drivetrain and lights before the start.
- Carry at least two spare inner tubes, a pump or CO₂ inflator, a tyre repair kit, a quick link for your chain and a multitool.
- If using a tubeless setup, carry tyre plugs, additional sealant and a spare inner tube.
- Bring a waterproof jacket, a warm base layer and gloves. In October, temperatures may drop significantly, especially at night and in mountainous areas.
- Check your brakes before long descents and maintain a safe speed. Be especially careful when riding at night, in fog, rain or on wet roads.
- Plan your rest and sleep strategy in advance. Over a 600 km distance, effective management of stops is just as important as maintaining a sustainable riding pace.
- If you experience severe drowsiness or reduced concentration, stop in a safe location and rest. Do not continue riding when fatigue affects your ability to control your bicycle safely.
- Avoid starting at an excessively high pace. Manage your energy throughout the entire distance. Pay particular attention to Gombori Pass, which comes approximately 97 kilometres before the finish.
- Allow extra time for unexpected situations, including mechanical problems, worsening weather or longer-than-planned rest stops.
- Take particular care during nighttime sections and in low-visibility conditions. Continuing to ride with inadequate lighting or severe fatigue can be dangerous.
Please remember that this is a self-supported event. Every participant is personally responsible for their own health, safety, navigation, rest and mechanical preparedness.
