Is that significant when running?

Yes, for an attempt like this where every marginal gain is necessary https://www.runnersworld.com/training/a20823445/does-draftin...

Even a 1% benefit is significant, considering that he beat the 7200 second goal by just 20 seconds (0.28%).

It's supposed to be good for about 2% at marathon pace. I'm not quite sure how long pace makers last in a traditional marathon, but I assume at least half way. So the rotating pace makers today explain maybe 1:12 of the two minute difference to his traditional best time.
