Man Cycles 5,850km Across France To Honor His Mother Who Died After 20 Years With Alzheimer’s

Frédéric de Lanouvelle spent 37 days cycling across France on a route that demanded up to 180 kilometres of riding a day, around 60,000 metres of climbing and countless hours alone on the road. But the former journalist and adventurer was chasing something far bigger than an endurance record. His bicycle was tracing a giant flower across the country, with every turn dedicated to his late mother.

De Lanouvelle’s mother was diagnosed with early-onset Alzheimer’s at just 50 and lived with the disease for almost two decades before dying in 2024 at 69. Before beginning the challenge, he spoke openly about what the illness had done to his family. He wanted his extraordinary journey to raise money for Alzheimer’s research, honour his mother and draw attention to a disease he believes still receives far too little support.

His Mother Spent Almost 20 Years Living With Alzheimer’s

De Lanouvelle knew exactly why he was taking on such a punishing challenge. His mother had been diagnosed with Alzheimer’s when she was only 50, an age when most people would not expect dementia to be part of their family’s future. She lived with the disease for nearly 20 years before her death in 2024, meaning her husband and children spent decades watching the illness change their family.

Her husband was there throughout the progression of the disease, while de Lanouvelle experienced the impact as her son. He has been blunt about how Alzheimer’s affects the people surrounding the patient as well as the patient themselves. During a France Bleu radio interview before his departure, he described carers and relatives as the “second victims” of the disease.

Two days before setting off from Étampes, south of Paris, de Lanouvelle also described the experience in much harsher terms. “I saw what the hell of Alzheimer’s was, I saw what it was for my mother, I saw what it was for my father,” he said during the interview. Those words provided a stark explanation for why the journey was about much more than cycling.

On 20 June 2025, he finally clipped into his bicycle and began the journey. Before leaving, he had predicted that the challenge would be difficult but also beautiful. Over the following five weeks, France would give him almost every kind of terrain and weather imaginable.

He Turned His Bicycle Route Into A Giant Flower

The unusual idea behind the challenge was built into the GPS route itself. De Lanouvelle did not want to simply cross France from one destination to another. Instead, he deliberately designed a route that would create a recognizable picture when viewed on a map.

The result was a huge flower stretching across the country. He called it La Fleur de l’Espoir, or the Flower of Hope, and dedicated the drawing to the Fondation Recherche Alzheimer. The route crossed 40 French departments and was initially reported at roughly 5,750 kilometres while he was still completing the challenge.

Creating a flower with a bicycle was considerably harder than simply choosing the quickest roads between towns. The petals required repeated loops and detours, meaning de Lanouvelle had to add kilometres that a conventional long-distance cyclist would normally avoid. Every unnecessary turn had a purpose because the shape would only become visible once the entire route was finished.

The idea also gave the challenge an image that could travel far beyond the roads themselves. Anyone looking at the completed GPS trace could see what the thousands of kilometres had created. What appeared on the map was not simply a record of distance, but a memorial dedicated to someone he had lost.

The Ride Meant Up To 180 Kilometres Every Day

The scale of the physical challenge was extraordinary even without the GPS drawing. De Lanouvelle rode between 150 and 180 kilometres each day for 37 consecutive days, pushing himself through a journey that ultimately accumulated around 60,000 metres of elevation gain.

That amount of climbing is close to seven times the height of Mount Everest when measured from sea level. The route also exposed him to a constantly changing French landscape, including hills, plains and wooded areas. He experienced both cold conditions and a heatwave during the five weeks he spent travelling.

Yet the terrain was not the part of the experience he spoke about most often afterward. De Lanouvelle repeatedly returned to the people he met during the journey, describing them as wonderful. The route brought him into contact with people who had direct connections to Alzheimer’s care, research and family life.

The physical demands were therefore only one part of the challenge. Every day added more distance to the flower while also moving him closer to the people and organisations connected to the disease he had watched affect his own mother.

His Journey Took Him Into Care Homes And Hospitals

Ten days into the ride, on Sunday 29 June, de Lanouvelle stopped at Résidence Harmonie, a care home where he met staff members and toured the facility. He learned more about how the residence organised personalised support for people living there before receiving encouragement from the staff to continue his journey.

That visit reflected a larger theme running through the route. His journey brought him into contact with care homes, university hospitals, researchers, nurses, carers and families. Rather than keeping the Alzheimer’s message separate from the physical challenge, he repeatedly brought the two together.

The encounters also helped put a human face on the reason for the ride. Alzheimer’s can easily become a story about statistics, medical research and future treatments. For the families living alongside the disease, however, the experience is much more immediate and personal.

The people de Lanouvelle met represented different parts of that reality. Some were providing daily care, some were researching the disease and others were living with its consequences through their own families. His route passed through all of those worlds while the flower gradually took shape across France.

He Highlighted A Huge Gap In Alzheimer’s Funding

De Lanouvelle also used the challenge to draw attention to the amount of money going toward Alzheimer’s research in France. During his France Bleu interview, he compared Alzheimer’s funding with private donations received by cancer research and argued that the difference showed how much more attention the disease needs.

He said cancer research attracts around €200 million a year in private donations in France, compared with about €10 million for Alzheimer’s. He also described Alzheimer’s as a genuine public health issue, pointing to the number of people affected and the continuing need for research.

Figures cited by the Fondation Recherche Alzheimer in 2025 put the number of people in France living with a neurodegenerative disease at 1.4 million. The same research found that only 34% of those people had received a formal diagnosis of their condition, according to the foundation.

For de Lanouvelle, those figures added urgency to the campaign. His fundraising target had been set at €10,000, and by the time he finished the ride, donations had passed €11,000 for the Fondation Recherche Alzheimer. The money was important, but so was the attention generated by a bicycle route large enough to become a national image.

The campaign gave him a way to connect his family’s experience with a wider issue. His mother had spent almost 20 years living with Alzheimer’s, and he wanted the challenge to put more light on a subject he believed was still receiving too little of it.

The Final Petal Closed After 37 Days On The Road

The final section of the flower was completed on Saturday 26 July in Villeneuve-sur-Lot. De Lanouvelle arrived at around 4 p.m., bringing 37 days of cycling across France to an end after weeks of heat, cold, hills and long stretches of road.

Before starting, he had predicted that the journey would be both difficult and beautiful. By the finish, both descriptions had proved accurate. The physical demands had been immense, but the people he encountered and the response to the Alzheimer’s campaign had become an important part of the experience.

The fundraising page had passed its €10,000 target, reaching more than €11,000 for the foundation. The ride had also succeeded in creating the visual tribute he had imagined before leaving Étampes.

But the distance reported during the ride was not the final number.

Guinness World Records Made The Distance Even More Remarkable

Guinness World Records later confirmed the completed distance at 5,850 kilometres, around 100 kilometres more than the figure that had been reported while de Lanouvelle was still riding. The organisation recognised the achievement as the largest GPS drawing by bicycle completed by an individual.

It was not his first experience of turning a bicycle route into a giant picture. In August 2023, de Lanouvelle and his daughter Mathilde rode a tandem across France and created a heart-shaped GPS drawing, taking the team version of the same record.

Mathilde was 16 at the time. De Lanouvelle has said he takes each of his children on an adventure when they turn 16, and he described the weeks he spent on the road with his daughter as indelible memories for both of them.

The 2025 challenge had a different emotional purpose. This time, de Lanouvelle was riding alone, and the person represented by the enormous drawing was his mother. The flower became a way to connect a world record with a family story that had begun with an Alzheimer’s diagnosis nearly two decades earlier.

His Record Replaced Another Emotional GPS Tribute

The previous individual record holder had also used a massive bicycle route to create a memorial. American cyclist Kristy Bellmer spent two months cycling around Europe and covered 4,707 kilometres, beginning her journey on 1 May, the birthday of her dog Slinky.

Bellmer used her route to trace the shape of Slinky across Europe in memory of her dog. The unusual achievement meant that the world’s largest individual bicycle GPS drawings had already carried a personal story before de Lanouvelle’s flower appeared on the map.

The two records now share an unexpected connection. Both turned an extreme cycling challenge into a tribute to someone who had died, with the shape only becoming visible when the enormous route was viewed from above.

There is also a striking difference between the two. Bellmer’s drawing represented a beloved dog across Europe, while de Lanouvelle’s flower stretched across France in memory of a mother who had lived with Alzheimer’s for almost 20 years.

Thousands Of Kilometres Became A Tribute To His Mother

De Lanouvelle began the ride with a bicycle, a GPS route and a very personal reason for taking on something most people would consider impossible. Thirty-seven days later, he had crossed France, raised more than €11,000 for Alzheimer’s research and secured a Guinness World Records title.

The final route measured 5,850 kilometres, but its most striking feature was what those kilometres created. A flower now stretches across a map of France, carrying the memory of a woman whose life was profoundly affected by Alzheimer’s.

For de Lanouvelle, the journey did not erase what the disease had taken from his family. It gave him a way to make that experience visible, one kilometre at a time.
