Only 1 or 2 day course some time every year. Because many is not interesting because they are for example only for women, only against knife and pistol etc etcAh, okay. Pictures a bit clearer now.
So you're looking specifically into their 3-day intensive course because there aren't any like that in your country, and you want to know if that specifically is worth it before you fly/drive down for a weekend to take part? Or are you looking to go down for the week-long instructor course as a beginner in Krav Maga, and are asking about that?
Can't comment on if it's good, but found this via the krav maga academy. Seems like they hold events similar to intensive courses fairly often, but here's a 5 day camp in Oslo next month.Norway
