Jean Marc did them all (and very fast)

Jean Marc Dumont was a new and promising star in our field and now he has already reached his zenith: on 4 september he did his very last bordermarker: bm602 (with a kayak). And he did them all astonishingly fast: in 3 years!

I already introduced Jean Marc (aka Marko) in the previous post and though he expected to finish in 2024, he apparently – like a sprinter – accelerated in sight of the finish.

How does Jean Marc feel about it? Well, he wrote me that he expected to feel proud but it was rather a feeling of sadness, now it’s all over: ‘quand c’est fini, c’est fini’. But he will certainly come back to the Pyrenees, not forgetting the bordermarkers. I liked very much his own certificate:

And now we can add him to the honoray list of all the brave men and women who did them all:

Javier and María-Jesús Sancho-Esnaola (estimation: 2010)
Charles and Josette Darrieu (estimation: 2010)
Jacques Koleck (2014)
Myself (first round 2014, second round 2022)
Michel Molia (2018)
Alain Gillodes (june 2021)
Corinne Gourgeonnet (september 2021)
Jean Marc Dumont (september 2023)

Thank you, Jean Marc, for sharing your adventures, all the best for the future and who knows: someday we might come across each other, somewhere ….. at the border.

Another new kid on the block: Jean Marc Dumont

A tip from Corinne Gourgeonnet: Jean Marc Dumont, a young man of 64 who is also aspiring to do all esfr-markers. He once started as a co-walker along the bordermarkers and now continues on his own with impressive trips on his MTB or by foot.


As a former air traffic controller, he retired at an early age (the ultimate dream of every Frenchman, so it seems) and never regretted that a single moment.
Now he has covered 74% of all esfr-bm’s (using the “parfait” excel-sheet on this page) and he expects to finish next year. That implies that he can well be the first to complete the esfr-bordermarkers after Corinne in 2021 and before Carlos & Conchita Roca, Sébastien Marc and Jérôme Loubière.
So far, only bm425 has given serious problems, getting in rough terrain and in fact in danger.

Special notice: he has his own mini-camper for his bm-outings: the MarKomobile which made me instantaneously jealous.

No blog, no website but you can still follow his adventures and progress on Strava. Good luck Jean Marc and let us know when you are approaching the finish.
