Run a Boston Qualifier: 18-Week AI Marathon Training Plan

Run a Boston Qualifier: 18-Week AI Marathon Training Plan

An AI plan calibrated to your exact BQ standard — VO2max intervals, threshold sessions and BQ-pace long runs over 18 weeks

Build my BQ training plan

The Boston Marathon is one of the most storied races on earth — and one of the few that demands a qualifying time to enter. Earning a BQ (Boston Qualifier) means joining a dedicated tier of runners who train with intention and race with precision. The Boston Athletic Association (BAA) sets qualifying standards by age group and gender. As a current reference point, the 2026 standard for men aged 18–34 is approximately 2:55:00 and for women and non-binary runners in the same bracket approximately 3:25:00 — but always verify your exact standard on baa.org before setting your goal, as these figures are updated every year. In practice, meeting the published standard is only step one: most years the number of qualifiers exceeds available spots, so the BAA applies a cutoff — an additional margin below the standard required to actually secure a race entry. The cutoff varies year to year, so targeting several minutes under your standard is the prudent strategy. RunRun builds a personalized 18-week plan calibrated precisely to your BQ target, with every training pace derived from your VO2max or a recent race result.

Why choose RunRun?

18-week performance-focused plan

4 to 5 sessions per week with full periodization: aerobic base phase, threshold and race-pace development, peak load weeks, and a 3-week taper. Every microcycle is designed to move you steadily closer to your qualifying standard.

BQ pace calibrated to your profile

RunRun calculates your target BQ pace from your VO2max or your most recent race time. Every BQ-specific session is locked to your exact standard — not a rounded estimate or a generic template.

Week-by-week progress tracking

RunRun logs each completed session and compares target pace versus actual pace. The plan recalibrates automatically if a week is too demanding or too easy, keeping you on the optimal path toward your qualifier.

VO2max intervals and threshold runs

Short repeats (30/30s, 1K repeats) to build VO2max, tempo runs and threshold blocks to raise your lactate threshold. The quality work that lets you hold BQ pace when it matters most — miles 20 through 26.

Optimized 3-week taper

Progressive volume reduction over the final 3 weeks so you arrive at the start line at peak freshness. Light sessions with strides maintain leg turnover without adding fatigue before race day.

Connect Strava, export to Garmin

Connect Strava to easily find and link your runs to your RunRun sessions. Export your sessions to your Garmin watch via Garmin Connect in one click — head out the door with your plan already on your wrist.

18-week BQ training plan overview

W1

Week 1 — Baseline and aerobic foundation

An assessment week to establish your starting point. Easy aerobic runs in zone 2, no interval work. The goal is to identify your reference paces and calibrate the entire plan to your actual fitness.

  • •A 45-minute easy run in zone 2 (conversational pace)
  • •50-minute easy run + 6×20-second strides
  • •Long run: 1 hr 20 min easy — weekly volume: 28–31 miles
W6

Week 6 — Threshold introduction and first BQ-pace block

First structured threshold session alongside the first BQ-pace block embedded in the long run. This is where your body begins to internalize its qualifying rhythm.

  • •40-minute easy run + 2×20-minute threshold intervals (5-minute recovery)
  • •45-minute easy run in zone 2
  • •Long run: 2 hrs including 20 minutes at BQ pace — weekly volume: 37 miles
W12

Week 12 — Peak training load

The highest training load of the cycle. Volume peaks around 47–50 miles with the most demanding VO2max session and a long run featuring an extended BQ-pace block to simulate race conditions.

  • •3×15-minute intervals at 95% VO2max (3-minute recovery between blocks)
  • •45-minute easy run + drills
  • •Long run: 2 hrs 40 min including 50 minutes at BQ pace — weekly volume: ~48 miles
W18

Week 18 — Final taper and race

Last week before your qualifier. Volume at a minimum, light sessions to stay sharp. Full rest 2 days out, an easy 20-minute jog the day before — then race day.

  • •30-minute easy run + 6 strides at race pace
  • •Active rest (walking, light stretching)
  • •Day before race: a very easy 20-minute jog — everything is in place.

Key tips for running your BQ

1

Verify your exact BQ standard on baa.org

The BAA publishes precise standards by 5-year age group and gender at baa.org. Do not rely on third-party tables — standards change each year. Your exact standard is your target pace, not an approximation.

2

Aim well below the published standard

Meeting the BQ standard does not guarantee a race entry. Each year the BAA applies a cutoff — only runners who beat their standard by a sufficient margin secure a spot, filled in order of fastest to slowest. Review recent cutoff data on baa.org and target at least 3 to 5 minutes under your standard to protect your registration.

3

Nail BQ pace in the final miles of your long runs

The ability to hold BQ pace for the last 30 minutes of a 2 hr 30 min long run is the most reliable predictor of race readiness. Progressively extend your BQ-pace blocks at the end of your long runs — this is the signature session of your entire build.

4

Practice race nutrition from your very first long runs

From 1 hr 15 min of running onward, practice taking gels and drinking on the move. Race-day fueling cannot be improvised — your gut must be trained to process carbohydrates under effort. Lock in your preferred products well before taper, and do not change anything in the final weeks.

5

Guard your sleep during peak training weeks

Muscle protein synthesis peaks during deep sleep. In high-volume weeks (47+ miles), aim for 8 to 8.5 hours per night without exception. Chronic sleep debt during a hard training block raises injury risk and blunts the physiological adaptations you are working to earn.

What is the Boston qualifying time for my age group and gender?
The Boston Athletic Association (BAA) sets BQ standards by 5-year age group and gender. As a reference, the 2026 standard is approximately 2:55:00 for men aged 18–34 and approximately 3:25:00 for women and non-binary runners in the same bracket — standards ease progressively with age across all divisions. These figures are updated annually: always check baa.org for the official, current standard that applies to your specific profile before setting your goal.
What is the Boston Marathon cutoff?
The cutoff is the additional buffer the BAA imposes when the number of qualified applicants exceeds available race spots. Earning a BQ does not guarantee registration: the BAA fills entries in order of the largest margin below the standard, trimming candidates until the field is full. The cutoff shifts year to year based on demand — review recent results on baa.org. A sound rule of thumb: target at least 5 minutes under your standard to give yourself a real chance of securing a bib.
Can RunRun help me hit a specific target time like a BQ?
That is exactly what RunRun is built for. Enter your BQ target, your VO2max or a recent race result, and your race date — RunRun generates a personalized 18-week plan with every session pace calculated specifically for you. Not a generic template: a program calibrated to your current fitness and your exact qualifying standard.
How many weeks of preparation do I need to run a BQ?
This RunRun plan covers 18 weeks — the recommended duration for a serious BQ build. It includes an aerobic base phase (weeks 1–4), a development block with threshold and BQ-specific pace work (weeks 5–14), and a 3-week taper (weeks 15–18). Ideally, start these 18 weeks already running 31–37 miles per week consistently.
How does RunRun calculate my BQ training paces?
RunRun uses your VO2max (maximum aerobic speed) or your most recent marathon or half-marathon time to derive all your training zones: easy aerobic, threshold, VO2max, and your specific BQ marathon pace. Your BQ pace is the speed you need to sustain for 26.2 miles on qualifier day — every key session in the plan references it directly.
When does Boston Marathon registration open?
Registration typically opens in the autumn for the following spring race. Exact dates shift from year to year — check baa.org for the official registration schedule. The window is short and entries fill quickly, so prepare your qualifying documentation well in advance.
