Two dudes mid to late 20s running 6 min/mile. They looked like they could lay down a sub 3 hour marathon no problem. They obviously run a lot.

Anyway they were running side by side in the middle of the trail. I came up behind them going 25 mph. This is a little known and usually deserted trail so got no problems going fast. I yelled on your left and they looked over their shoulder and saw me with probably good 5 seconds of lead time. The right guy stayed where he was (more or less in the middle) and the left guy didn't move either until he looked at me again with a second to spare and awkwardly moved left just as I was on top of them. Had to hit the brakes swerve and thread the needle between him and the fence to avoid all three of us going down.

The only reason this wasn't a crash is that these sort of encounters happen all the time and I'm prepared to get out of it no matter what the other party does. Just really surprising that these two didn't know what to do. That was properly strange.
