The two weeks trip to Siurana turned out to be a very successful one. After a couple of days of working on „La Rambla“ David could finally tick his first 9a+ ever. And right before leaving he finished the trip with a quick ascent of „La Reina Mora“, just next to La Rambla.

4 x 8B in Font

This year’s April and May I’ve spent 3 weeks in Fontainebleau to try demanding boulder problems on my personal limit. It was super fun and motivating to see and feel how I was improving and I really enjoyed the challenge to go this specific step further in my personal bouldering, even if there were sometimes hard and frustrating moments. I also took my camera with me and recorded some ascents. Here is a short video clip featuring four 8B’s I’ve done in the forest. I hope You like it! Cheers David ;-)
