Modifying third person character's global anim rate?

I’ve just started getting into Unreal 4 and C++ for a school project and the first thing I’m working on is a sprint function. So far, I have the speed increase done, but I want to make the animation speed up as I do so. I know I need to edit the global anim rate but I can’t figure out how to access it in C++, numerous google searches have lead me nowhere.

Late reply on here, but in case anyone else has the same problem… You can access it through the Skeletal Mesh Component → Global Anim Rate Scale
