Firman is a tricky course. It's way more technical than one would think. The start is bumpy, and then the backside of the course is dusty and has a hard hairpin 1k into it after a short uphill. You drop back down pretty much immediately before you slowly climb a minor hill that drops down onto a beach with loose sand before you go up a little roller and then up the big hill. The descent is not fast, and then you get onto a trail that repeats the previous loop. The finish is on uneven ground.
