Pace chart
50K pace chart
Fifty kilometers is a marathon plus an hour of honesty. This chart steps in ten-second increments rather than five, because nobody paces an ultra to the second, and it runs slow enough to include the hiking.

The 50K is the only ultra distance that still behaves a little like a road race, which is why it is on this site and the 100-miler is not. Many are run on trails, most include walking, and the average pace that comes out of the far end usually surprises people who arrived from a marathon background. Plan with the slower half of this table, not the faster.
The step is ten seconds a mile, not five. That is deliberate: over 31 miles, five seconds a mile is more than two and a half minutes, and pretending to pace an ultra more precisely than that is theatre.

The marathon column is the one to sit with. The same pace that produces a comfortable marathon produces a 50K time about a fifth longer, and that final fifth is where every 50K is actually decided.
