How to make a first person VR character move along a spline?

At the moment I am doing my graduation project. I am creating a VR-experience to physically activate elderly is nursing homes. The idea is to create an experience, in which the user has to use exercise pedals to cycle through the environment on a fixed path.

I know how to design the landscape and everything in it, but I am inexperienced using blueprints. I want my first person VR character to move along a spline, so they can use the exercise pedals to move around and use the HMD to look around. It’s quite simple I think, but I don’t know where to start. I have also checked out some tutorials, but none of them explains how to make a first person character move along the spline.

Any specific explanation on how to do this, is welcome. I can use any help.

Thanks in advance!
