This cheerful couple from Barcelona started in 2016 with searching and photographing esfr-bordermarkers. This is their website.
First, they covered the eastern Pyrenees, east of Andorra. Then they made a crucial decision: let’s try to do all 602 esfr-bordermarkers. They worried a bit about their age (they look 55 but are actually a tiny bit older) and feared the long trips into the high mountains. But why not try? Jacques Koleck started when he was 71 and Michel Molia was 73 and they both completed the whole esfr-border.

Since yesterday you can follow their progress on this website-map:

The red markers are the ones still to be done, the green ones have been covered. You will also find yellow lines (bm’s done walking) and violet lines (done by car).

A few days ago, they reported me that they had found their 301st bordermarker implying they are halfway of the official 602 bordermarkers. 

Congratulations! You are going strong!

To be honest (and they know it): In fact there are more than 602 bordermarkers (double ones, extra ones, intermediate ones: see this page) but this one deserved to be celebrated.
