How a road relay works

In a typical road Ragnar, a team of 12 runners in two vans covers about 200 miles over 36 legs. Runners go in order: runner 1 runs legs 1, 13 and 25; runner 12 runs legs 12, 24 and 36. Van 1 carries runners 1–6 and van 2 runners 7–12, so each van alternates between running and resting for about 5–7 hours at a time.

Includes about 1 minute per exchange. Real races also include van traffic, queues at exchanges and course-specific leg lengths.

Tips for accurate relay planning

  • Use honest paces — current 10K race pace plus 30–60 s per mile is a sensible starting point for most runners over three legs.
  • Add time for night legs and hills. Headlamps, darkness and elevation slow most runners.
  • Update during the race. Enter actual leg times as you go; the rest of the schedule re-calculates so the next van arrives on time.

For trail Ragnars, Hood to Coast or any relay, paste your own leg list. Related: pace calculator, race fueling, ultra pace planner.

FAQ

Ragnar Relay questions

In a typical road Ragnar, a team of 12 runners in two vans covers about 200 miles over 36 legs. Each runner runs three legs in rotation: runner 1 runs legs 1, 13 and 25, and so on. Van 1 carries runners 1–6 and van 2 runners 7–12.

Use a realistic pace for each runner’s current fitness and add time for night legs, hills and fatigue in later legs. Many teams add 30–60 seconds per mile to each runner’s usual race pace.

Small errors add up over 36 legs. Update each runner’s actual leg times during the race and the schedule re-calculates, helping the next van arrive at exchanges on time.
