Marathon - Sport photography - Tips or advices?

Tomorrow is London's marathon. A friend of mine is running it and would like to surprise him with a few shots. Issue is, I'm more a landscape photographer than anything else. I have a bit of experience with portrait shots, but usually friends or family during trips, standing still. I'm definitely not used to moving targets: the few times I tried my luck on animals for some wildlife photography led to poorly focused pictures (when no other issues).

Would you have any tips / advices to make sure I capture great shots of him? I will naturally try a few shots of other runners before he arrives to my spot so that I get some practice.

For background, I own a Sony Alpha 7 IV with a Sony 28-70mm Zoom Lens, a Tamron 70-180mm f/2.8, and a Tamron 17-28mm f/2.8 (I suspect it will be less useful this one).

Appreciate any feedback and happy to share some of the shots later on in this thread.
