I tried to do the math as well and I can't see how 60k steps on average works. From what I can see online your 2 steps per second is somewhat on the slow end but even at an ideal speed (apparently 180 steps per minute / 3 per second) you are still looking at 5.5 hours of running. This seems achievable for someone very fit who wants to burn the weekend on an ultra long distance run but there is no way they are doing this daily.
