Well, we have Szeth who mentions that plate hampers with his surge abilities so a windrunner isn't very likely to be wearing plate. But if he were, you'd just aim the coins at the visor slits.
By higher endurance, I mean that a mistborn should be able to keep flying around as long as he has metals, whereas a windrunner's out of juice once stormlight is gone. From my impressions, stormlight is significantly scarcer than available metals that you carry around.
And while default stormlight healing is very powerful, it has to take some time and/or have a limit to the amount of damage it can heal, otherwise all radiants must be functionally immortal. I claim that a mistborn with sufficient time would be able to do enough damage to either outpace the healing speed or exhaust the available stormlight.
I concede that I forgot about reverse lashings, however, if all it does is give an object a large gravitational pull, a misborn burning atium would be able to see that effect in advance and be able to plot a course to slingshot the coins to the accurate location, just like Nasa did with several space probes, slingshotting them using the gravity of Jupiter to give them an even higher speed.
Finally, regarding the windrunner lashing himself to the mistborn - I admit that proves a worry. The only solution I can come up with off the top of my head is to push various coins at the windrunner, resulting in either enough damage to stop the pursuit or it comes down to which is stronger, a lashing or a push. @Pathfinder the phrasing used was that he lashed him that direction: "Kaladin jumped to put his feet towards the Shardbearer and Lashed himself that direction many times in quick succession".
Ultimately I guess my argument relies on the presence of Atium, which more or less grants the user invincibility and unerring accuracy, the limited availability of stormlight, and the abundance of metals.
Edit: So I googled that it takes around 3000 newtons of force to crack ribs, so maybe 5000 newtons to crack leg bones. Given that Kaladin is probably around 80-100 kg, we're looking at 60 m/s^2 of acceleration using all the stormlight he could muster.
On the other hand, Vin/Elend were able to ironpull several tons of metal in opening the lord ruler's caches. Even if we're just talking 1 ton of metal, they would be able to exert ~10k newtons worth of force, which is at least comparable if not straight up stronger than lashing.
