Episode summary

Trail and environment: a dual passion that becomes a project

Morgane Lelièvre has been trail running for several years, with a predilection for long distances. After living in the Pacific for 9 years, she embarked on her first eco-sport project in Australia, following the fires that left a deep impression on her: 250 km of running to raise funds for the WWF. On her return to France, she began to dream bigger: to combine her passion for trail running and her commitment to the environment in a large-scale project.

The Traversée Verte: a sporting and civic adventure

She chose the Méridienne Verte, a historic route from the north to the south of France, little known to the general public. She adapts the route to alternate between towns, villages and nature, with one objective: to collect as much garbage as possible. At the same time, she prepares upstream presentations in schools, to raise awareness of pollution and environmental protection among the very young.

Even though her ultra-trail experience gives her a good base of endurance, Morgane leaves nothing to chance. She trains, strengthens her back to carry a 10-13 kilo pack (equipment, food and garbage), and runs with a load to simulate real-life conditions. The result: no major physical problems during the crossing.

Autonomous logistics (or almost)

Morgane sets off alone, self-sufficient, with an almost daily bivouac, water filter, sleeping bag and two bags: one for her equipment, the other for waste. To feed herself, she anticipates as much as possible, favoring bakeries with her cotton bags, but sometimes having to carry several days’ worth of food. She quickly adapts her routines: emptying waste bags as soon as a garbage can is available, optimizing tidying, and adjusting her timetable to meet her school commitments.

Collect, sort, report

In all, she collected 428 kg of garbage. Plastic bags, cigarette butts, food packaging… The volume doesn’t necessarily reflect the seriousness of the pollution, as most of the waste weighs next to nothing. At the same time, she reports numerous illegal dumps via the TrashSpotter app, and alerts town councils. Several have responded positively, encouraging her to continue in this direction.

Striking exchanges in schools

Along the way, Morgane will be visiting around ten schools. For her, this educational aspect is fundamental: ” Its at school that you learn the right reflexes “. The children greet her with enthusiasm and curiosity, sometimes with drawings or placards. Some exchanges touch her deeply, like this little note from a kindergarten pupil: ” Thank you for what you do for nature “.

Unforgettable encounters and moments

The adventure isalso one of sharing: trailers who come to run alongside her, families who support her, strangers who become friends. The landscapes and the sometimes magical bivouacs punctuate her route, like this evening in the Cher on the banks of a stream. She also recalls the emotional surprise of meeting up with her brother and sister-in-law on a day when she was feeling a bit down, and the final finish, surrounded by her family.

The hardest times

While the body held out, morale sometimes wavered. The passage through the Paris region, with its heavy pollution, was a difficult time. As were certain mishaps in the field: impassable paths, electric fences, fields to cross, or losing her phone in the middle of nowhere. But every time, Morgane hangs on, reassures herself, finds a solution, and keeps going.

A project that leaves its mark… and opens doors

On her return, she confesses to having been profoundly transformed by this adventure. Calmer, more aligned, more determined too: she decided to give up “food jobs” and devote herself to professional projects in line with her values. Her message has also been emulated: some trail runners have written to tell her that they now pick up garbage when they train.

“Enjoy, move, and make small gestures”.

In conclusion, Morgane has a simple yet powerful message: ” Enjoy being in nature, move at your own pace, and don’t compare yourself. And if you care about the environment, do your bit, even on a small scale. Every gesture counts.
