Tips for shooting action sports on 16mm?

[Relentless]

For my final project, I got the go-ahead from my CP1 Professor to shoot some mountain biking. We have Bolexs and Kodak Vision 2, 200T Color Negative film. I've got exposure + control of the camera down for general shooting - but I'm curious if you have any tips? I've shot action sports a decent bit with HD, but never on 16mm.

Thanks
