Half Marathon Training Plan for Intermediate Runners

Share

A 12-week intermediate half marathon training plan with tempo runs, intervals, and progressive long runs. Designed for runners looking to improve their half marathon time.

Half Marathon Training Plan for Intermediate Runners

A 12-week schedule for evaluating race-specific training against your preparation and goals. A personal record is not guaranteed.


Plan Overview

Goal: Improve your half marathon time through balanced training that builds endurance, speed, and race-specific fitness

Who This Plan Is For:

  • Runners currently averaging 25-35 miles per week
  • Those who have completed at least one half marathon
  • Runners comfortable with tempo runs and intervals
  • Athletes with 1+ year of consistent running

Prerequisites:

  • Running 4-5 days per week consistently
  • Recent half marathon or 10K time for pace calculations
  • Able to comfortably run 10 miles
  • No current injuries

Weekly Structure:

  • 5 running days per week
  • Weekly running totals separate miles, metric repetitions and timed recovery; record actual distance rather than treating timed work as fixed mileage
  • Usually two faster sessions; some weeks also include a faster long-run finish. Review the combined demands and recovery before choosing this schedule
  • 1 long run (up to 14 miles)

Effort and Session Accounting

Easy means a comfortable effort at which conversation remains manageable, not a particular heart-rate zone or a fixed percentage of this schedule. Moderate, tempo and half-marathon effort are different intended efforts within a plan; none is established by assigning an arbitrary zone number or an aspirational finish time. Review the suitability of the faster sessions before choosing this template. If the intended effort is unclear or inappropriate, resolve it with suitable training support rather than guessing a target pace.

Distance and time are separate instructions. A row listing minutes is completed by time, with actual distance recorded afterward. Do not add miles to reach the old estimate. A mixed row such as “2 miles + 21 minutes” contains both components: the miles are easy preparation/cool-down and the minutes contain the specified repetitions and recoveries. Weekly totals sum those components separately; they do not convert time into invented mileage. Optional cross-training is recorded separately from running.

For distance-based runs with strides, the listed distance is the entire outing, including easy running, pickups and easy recovery. Strides are optional familiar accelerations, not all-out sprints. Begin with easy running, recover by walking or easy jogging until ready for another comfortable repetition, and finish easily. Omit remaining pickups if appropriate preparation/recovery will not fit the outing; do not add them after completing the stated distance merely to tick a count. Record any actual change.


Metric repetitions remain in meters so you can use track markings directly. 1 mile = 1609.344 meters. For example, 4 miles + 6600 meters is approximately 8.10 miles, not 7.5 miles. Timed jogging adds actual distance that must be recorded; it cannot be converted without a measured pace/distance. The distance column below is the full fixed-distance component, with any timed component stated separately.

Recovery is between repetitions only unless a row explicitly describes repeated work-plus-recovery pairs. The final repetition is followed by the stated cool-down. Multi-block sessions specify the transition between blocks. No extra repetitions are added merely to reach an old mileage estimate.

Week-by-Week Schedule

Week 1: Establish Baseline

Weekly Running Total: 30 miles + 24 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 5 miles
Wednesday Tempo: 2 mile warmup, 3 miles tempo, 2 mile cooldown 7 miles
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday Fartlek: 2 miles easy, 6 × (2 min hard + 2 min easy), 2 miles easy 4 miles + 24 min
Sunday Long run (easy) 9 miles

Focus: Review whether the opening workload and intended efforts fit your recent training. Completing a workout does not measure your physiological thresholds.


Week 2: Building Rhythm

Weekly Running Total: 32 miles + 6600 meters.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 5 miles
Wednesday Intervals: 2 miles easy, 5 × 1000 m at interval effort with 400 m jog between reps (4 recoveries), 2 miles easy 4 miles + 6600 m
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday Tempo: 2 mile warmup, 4 miles tempo, 2 mile cooldown 8 miles
Sunday Long run (easy) 10 miles

Focus: Keep the intended interval effort and recovery consistent. The repetition distance alone does not establish a VO2max stimulus.


Week 3: Increasing Load

Weekly Running Total: 39 miles + 9 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 8 strides 6 miles
Wednesday HM-specific: 2 miles easy, 4 × 1 mile at HM effort with 2 min jog between reps (3 recoveries), 2 miles easy 8 miles + 6 min
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday Threshold: 2 miles easy, 2 × 2.5 miles tempo with 3 min jog between reps, 2 miles easy 9 miles + 3 min
Sunday Long run (easy) 11 miles

Focus: Record how the planned HM effort feels across the repetitions, including the effect of recovery breaks.


Week 4: Cutback Week

Weekly Running Total: 21 miles + 38 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 5 miles
Wednesday Fartlek: 10 min easy, 6 × (1 min moderate + 2 min easy), 10 min easy 38 min total
Thursday Easy run 4 miles
Friday Rest -
Saturday Easy run 4 miles
Sunday Long run (easy) 8 miles

Focus: This week reduces the listed running. Review your response before continuing; feeling stronger next week is not guaranteed.


Week 5: Building Race Fitness

Weekly Running Total: 35 miles + 6000 meters + 7.5 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 8 strides 6 miles
Wednesday Intervals: 2 miles easy, 6 × 1000 m at interval effort with 90 sec jog between reps (5 recoveries), 2 miles easy 4 miles + 6000 m + 7.5 min
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday HM simulation: 2 mile warmup, 5 miles at HM pace, 2 mile cooldown 9 miles
Sunday Long run (easy) 11 miles

Focus: Record execution of the 5-mile HM segment. This is practice, not a validated half-marathon readiness test.


Week 6: Peak Quality Week

Weekly Running Total: 37 miles + 10400 meters.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 8 strides 6 miles
Wednesday Ladder: 2 miles easy, 800–1200–1600–1200–800 m at interval effort; jog the distance of each preceding rep between reps only (800 + 1200 + 1600 + 1200 m), 2 miles easy 4 miles + 10400 m
Thursday Easy run 6 miles
Friday Rest or cross-train -
Saturday Progressive tempo: 2 mile warmup, 5 miles (moderate to tempo), 2 mile cooldown 9 miles
Sunday Long run: 10 miles easy + 2 miles at aerobic pace 12 miles

Focus: Review the combined ladder, progressive tempo and long-run demands. Completing them does not establish race readiness.


Week 7: Sustained Efforts

Weekly Running Total: 41 miles + 3 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 6 miles
Wednesday HM-specific: 2 miles easy, 2 × 2.5 miles at HM effort with 3 min jog between reps, 2 miles easy 9 miles + 3 min
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday Tempo: 2 mile warmup, 4 miles tempo, 2 mile cooldown 8 miles
Sunday Long run (easy) 13 miles

Focus: The two HM-effort segments include recovery between them. Completing five miles of work does not prove you can hold that effort for a half marathon.


Week 8: Cutback Week #2

Weekly Running Total: 22 miles + 44 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 5 miles
Wednesday Fartlek: 10 min easy, 8 × (1 min moderate + 2 min easy), 10 min easy 44 min total
Thursday Easy run 4 miles
Friday Rest -
Saturday Easy run 4 miles
Sunday Long run (easy) 9 miles

Focus: Review your response to the preceding weeks before continuing into the final block.


Week 9: Race-Specific Block

Weekly Running Total: 40 miles + 3600 meters + 8 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 8 strides 6 miles
Wednesday Combo: 2 miles easy; 3 × 1200 m at interval effort with 2 min jog between reps; 2 min easy transition; 2 × 1 mile at HM effort with 2 min jog between reps; 2 miles easy 6 miles + 3600 m + 8 min
Thursday Easy run 5 miles
Friday Rest or cross-train -
Saturday Tempo: 2 mile warmup, 5 miles tempo, 2 mile cooldown 9 miles
Sunday Long run: 11 miles easy + 3 miles at HM pace 14 miles

Focus: This is the longest listed run, with a faster finish. Assess that added demand against your preparation and recovery.


Week 10: Final Hard Week

Weekly Running Total: 38 miles.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 8 strides 6 miles
Wednesday HM-specific: 2 mile warmup, 6 miles at HM pace, 2 mile cooldown 10 miles
Thursday Easy run 5 miles
Friday Rest -
Saturday Easy run + 6 strides 5 miles
Sunday Long run (easy) 12 miles

Focus: Record effort and execution across the six-mile HM segment; use the whole training history when reviewing race plans.


Week 11: Taper Begins

Weekly Running Total: 32 miles + 6 minutes.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 5 miles
Wednesday Sharpener: 2 miles easy, 4 × 1 mile at HM effort with 2 min jog between reps (3 recoveries), 2 miles easy 8 miles + 6 min
Thursday Easy run 5 miles
Friday Rest -
Saturday Easy run 4 miles
Sunday Long run (easy) 10 miles

Focus: The schedule retains HM-effort repetitions during the taper. Review their suitability rather than assuming a sharpening effect.


Week 12: Race Week

Weekly Running Total: 12 miles + 2400 meters + 4 minutes before race; 25.1 miles + 2400 meters + 4 minutes including the listed 13.1-mile race. The race distance is rounded for this template.

Day Workout Distance
Monday Rest -
Tuesday Easy run + 6 strides 4 miles
Wednesday Tune-up: 2 miles easy, 3 × 800 m at HM effort with 2 min jog between reps (2 recoveries), 1 mile easy 3 miles + 2400 m + 4 min
Thursday Easy run 3 miles
Friday Rest -
Saturday Shakeout + 4 strides 2 miles
Sunday HALF MARATHON RACE DAY! 13.1 miles

Race Execution: Use the pacing strategy guide and race-day decision guide. No mandatory first-mile offset or late surge is part of this schedule.


Interpreting the Workouts

Repetition length, effort and recovery are separate parts of a session. A label such as “interval” or “tempo” does not prove a measured physiological threshold or guarantee a particular adaptation. HM-effort work is practice within a suitable plan, not proof that you can sustain a pace for an entire race.

A progressive or faster-finish long run adds demand beyond an easy outing. This schedule sometimes places faster Saturday work before Sunday's long run; assess that combination against your preparation and response. Completing the arithmetic does not establish that the dose or spacing is suitable for you. Review uncertain sessions with appropriate training support rather than using the intermediate label as clearance.


Nutrition and Race Logistics

Plan familiar meals, food and fluids around your expected duration, tolerance, conditions and available opportunities. A distance label does not establish a universal gel count, breakfast drink amount or supplement requirement. Use the race-week checklist to record your practiced plan and alternatives; it links duration-based sports-nutrition guidance and measured-fluid planning context.

There is no compulsory low-fiber dinner, fixed breakfast interval, automatic drink at every station or immediate recovery quota in this template. If a specific nutrition change is needed, resolve it in the context of your existing plan and appropriate professional advice. Familiar choices are useful, but necessary safety adjustments take priority over a “nothing new” slogan.

Use the race-day guide for morning and in-race decisions. Work backward from actual organizer deadlines for pickup, transport, bag check and corral access, allowing realistic buffers. The event's current instructions take priority over an example arrival time. Preparation should fit you and the event; no automatic warm-up/stride dose is added by this checklist.

  • Verify the race date, wave and current official instructions.
  • Record pickup, transport, bag and corral deadlines.
  • Check weather, conditions and whether the plan still fits.
  • Prepare suitable gear and any practiced food/fluid arrangements.
  • Keep contact, finish collection and return-transport details available.
  • Seek appropriate assistance if unwell; completing the plan is not medical clearance.
