As long as you dont intentionally proke the black mambas you should be fine. Snakes first instinct is to run away from humans not chase them down.

~~I've heard that's not the case with Black Mambas, that they can be aggressive without provocation. I'll try and find a reference, or I'll delete this for being wrong...~~

Looks like I was mostly wrong. They are shy but can be aggressive and most chase stories may be attributed to people being in the way.
