Bryan Cranston's Running Pace was unfeasible

Just watched half of the first episode and I've got to say if this continues to feature (which I think it will giving his marathon training), I'm going to struggle with the unrealistic nature of this.

His pace running up to that house I estimate was ~ or even under 6 minute mile pace. I know they've got the hood up to hide the actual (much younger) runner but no way a guy his age is doing that in the MIDDLE of his run.

We can surmise that must be the case because as a Judge there is no way he is living within at least a couple of miles of that project, and he then had to continue on to his city centre court offices. I'm saying conservatively at least a four mile run. However, he said he was marathon training so probably longer.

No way he is running at that pace. They really dropped the ball here.
