Eliud has amassed an incredible record in marathons with pacers. I don’t know if he has yet run a marathon without benefit of pacers.
How would he fare if he had to carry the pace by himself? In an unpaced race all other runners would just sit on him, try and keep up, and then try and out kick him at the end. If he had to race Mo or KB head to head, would he be strong enough to grind them down to avoid a sprint to the line? My sense is he would have trouble outkicking them if it came to that.
