Pacing Advice

  • Start conservatively for the first 3 miles.
  • Use goal pace as a rhythm, not a sprint target.
  • Practice holding pace late in long runs with fast-finish sections.

Nutrition Tips

  • Practice fueling during long runs before race day.
  • Consider carbohydrates during races lasting longer than about 75-90 minutes.
  • Hydrate according to conditions and avoid trying new products on race day.

Common Mistakes

  • Racing the first 5K too hard.
  • Not practicing gels or fluids before race day.
  • Skipping easy mileage and relying only on workouts.

Sample Training Week

  1. Easy run.
  2. Workout: threshold intervals or goal-pace blocks.
  3. Recovery run or rest.
  4. Medium-long aerobic run.
  5. Easy run with strides.
  6. Long run within your level's range, practicing fueling when needed.
  7. Rest or very easy cross-training.

How To Progress

  • Build long-run distance gradually before adding fast-finish sections.
  • Progress goal-pace work from short blocks to longer blocks across the plan.
  • Practice fueling on long runs once race duration is likely to exceed 75-90 minutes.

Race-specific workouts

Use these as examples of the workout types that support this distance. Adjust volume and recovery to match your level.

WorkoutExample SessionPurpose
Goal-pace blocks3 x 2 miles at half-marathon pace with 3-4 minutes easy jog.Practice race rhythm before the full distance fatigue arrives.
Threshold intervals4-6 x 1 mile at threshold effort with 60-90 seconds easy.Build the strength to keep goal pace comfortable longer.
Fueling long runLong run with planned gel, chew or sports drink practice.Make race-day fueling familiar before the event.

Taper guidance

  • Begin reducing volume 10-14 days before race day.
  • Keep a short goal-pace touch in the final week.
  • Do not test new fueling, shoes or workouts during taper.
