What does this pace feel like?

A 4:59/km pace for the marathon is a strong, demanding effort sustained for three and a half hours. The pace itself is manageable for a fit runner — the challenge is maintaining it through the final 10 km when glycogen stores are depleted and fatigue sets in. This is where months of long runs and tempo work pay off.
