ULTRA

1000km 8000m 100hrs
17 - 21 MAY 2025

The race

The race will start on Saturday, May 17 in a mass start format at 18:00. Riders will have 100 hours to make it back in time for the finishers party on Wednesday, May 21 at 22:00. This means that riders have one evening and almost four full days to finish on time.

As this is a self-supported race, riders must rely on their own abilities and are only allowed to use commercial services to meet their needs. As usual with these types of races, no prizes will be awarded to the winners.

The route

Utrecht Ultra offers a mix of free and fixed routes, with approximately 98% of the course on tarmac. Riders begin on a fixed route from the starting point in Utrecht, after which they will have to pass through three different checkpoints (CPs) located in neighbouring countries.

The CPs are strategically placed, requiring riders to carefully plan their own routes between them. Each CP is staffed by volunteers and features a short mandatory parcours.

CP1 is located in Germany’s Eifel region, taking riders up and down the hills surrounding the Ahr river. CP2 lies deep in Luxembourg, known for its smooth tarmac and plentiful switchbacks. And finally, CP3 in Belgium’s Ardennes features iconic climbs such as Stockeu and La Redoute.

After passing through the final CP, riders will return to The Netherlands to follow a final fixed route back to Utrecht.

Find a preview of the route below. Definitive routes will be shared mid-February.

Frequently asked questions

What does self-supported mean?

During the race, riders must remain self-supported. This means no outside help is permitted, such as using private lodgings, getting resupplies from friends or drafting other riders. All food, drinks and equipment must be carried with you or acquired at commercially available services. Any service used during the race must be available to all riders. This means booking accommodation or eating at restaurants is allowed. However, it is not allowed to book accommodation along the route before the race starts.

Do I have to plan my own route?

Yes, Ultra Ultra offers a mix of free and fixed routes, divided into five parcours that make up approximately 50% of the total race route. The five parcours are: a start parcours out of Utrecht, three parcours around the checkpoint locations, a finish parcours into Utrecht. Everything in between has to be planned by you.

Can I ride Utrecht Ultra as a pair?

Yes, Utrecht Ultra has a dedicated pairs category. Pairs riders must also remain self-supported but are allowed to act as a unit, sharing things like food, equipment and information between themselves. They can help each other and ride in each other’s slipstream, but no support is allowed from outside the pair.

What can I expect at the staffed checkpoints?

Along the CP1, CP2 and CP3 parcours you will find a staffed checkpoint. These checkpoints will open as soon as the first rider arrives and will close again at set cut-off times. At each checkpoint you will get your brevet card stamped by our volunteers and on some of the checkpoints there may be services available to riders. Sleeping at a checkpoint is usually not possible, but filling up your water bottles should be no problem. Exact details about each checkpoint will be shared in the race manual.

When can I expect more information about the route and other race details?

We aim to share the definitive route and the race manual three months before the race starts. For Utrecht Ultra that means mid-February. In the race manual you will find details about the checkpoints and cut-off times, the race rules, mandatory items, accreditation, sponsor deals and of course the finisher's party.

Which type of bike is best suited for Utrecht Ultra?

It’s up to you to decide which type of bike you choose, as long as it’s a non-electric upright bicycle. Most people opt for a road bike, but we’ve also seen lots of gravel bikes and even some time trial bikes.

What is a GPS tracker and can I provide my own?

GPS trackers are provided by Follow My Challenge and we do not allow people to provide their own. They are not navigational devices and are only there to provide real-time tracking of all riders via an online tracking map. It is highly recommended to bring your own navigational device, such as a bike computer or phone, since various mandatory parcours must be followed during the race.

I registered for Utrecht Ultra XL, can I also register for Utrecht Ultra?

Of course you can, and we’d love to see you at both! We think both races are doable in one year, with enough time for recovery in between. And as an added bonus, everyone who registers for both races will receive an exclusive Utrecht Ultra T-shirt.

I would like to volunteer, where do I sign up?

Utrecht Ultra wouldn’t be possible without our volunteers. If you would like to get involved and support the race at one of the various locations that the event covers, please send an email to ruben@utrechtultra.com.
