Marius is a great guide, that will have patience and will adapt to your needs. In my case, I wanted to improve my skills on the enduro trails from Poiana Brasov. The results were great and the new information was mind blowing.
My advice is stop investing in your bike and start investing in your skills. 😉
If you just started MTB or you are shredding Sinaia like a maniac, do yourself a favor and try Massif. Your riding will get better and safer.
I’ll definitely do it again this season.
