Daniels vs. Pfitzinger vs. Hansons: Which Marathon Plan Fits You

Three books sit on the shelf of almost every marathoner chasing a time goal: Daniels' Running Formula, Advanced Marathoning (Pfitzinger and Douglas) and Hansons Marathon Method. All three start from the same premise, most of your mileage easy, and arrive at very different weeks. One gives you two long quality sessions and leaves the rest to you. Another writes out every single day, with long runs of 20 to 22 miles. The third caps the long run at 16 miles and makes you pay for it with six running days a week.

The wrong choice usually shows up around week 10, when the plan demands something your schedule, your injury history or your mileage base can't deliver. The comparison below puts philosophy, weekly structure, long runs, key workouts, mileage and plan length side by side, with a source for every number, and ends with a decision rule.

Key takeaways

• Pfitzinger is the most prescriptive: 18 or 12 weeks written day by day, long runs up to 22 miles (35 km) and a midweek "medium-long run."
• Daniels (the 2Q plan) is the most flexible: two quality sessions a week, both long, and you distribute the remaining mileage.
• Hansons trades the 20-miler for a 16-miler (26 km) and six running days, with a marathon-pace tempo every week and no full recovery between hard sessions.
• Choose by your real constraint: little weekend time (Hansons), a preference for deciding things yourself (Daniels) or a need for a fixed script (Pfitzinger).

The three methods side by side

What each method believes

Daniels: get the intensities right, decide the rest yourself

Jack Daniels is an exercise physiologist and Olympic medalist in modern pentathlon, and he published the first edition of Daniels' Running Formula in 1998 (Wikipedia). The fourth edition (Human Kinetics, 2022) organizes all training into five intensities, E (easy), M (marathon pace), T (threshold), I (interval) and R (repetition), with 31 training plans and a dedicated marathon chapter (Human Kinetics). Every pace is derived from a recent race result rather than a goal, which is the logic the Magic pace calculator reproduces.

The hard days are the quality sessions, or "Q" workouts. Daniels describes the structure himself: keep Q1, Q2 and Q3 in the order written, schedule E days between them, and do whatever warm-up and cool-down you feel is adequate (book excerpt at Human Kinetics). The same chapter includes an 18-week program for first-time marathoners. The plan most time-goal runners actually follow, though, is the 2Q: 18 weeks, two Q sessions a week, in versions defined by peak mileage (40, 55, 70, 85, 100, 120 and more than 120 miles). The rest of the week's mileage is yours to split however you like (detailed review of the 2Q plan).

Pfitzinger: endurance through mileage, every day written out

Pete Pfitzinger ran two Olympic marathons (11th in 1984, 14th in 1988) and went on to become an exercise physiologist (Wikipedia). With journalist Scott Douglas he wrote Advanced Marathoning; the third edition came out in 2019 (Trail Runner) and the fourth in 2025. The publisher's summary covers the offer: 18- and 12-week day-by-day schedules in four weekly mileage tiers (up to 55 miles, 55 to 70, 70 to 85, over 85), plus expanded guidance on adjusting the schedules and new material on heart rate training (Human Kinetics). Runners name each plan by weeks and peak mileage: 18/55, 18/70, 12/55.

The signature workout is the midweek medium-long run: 10 to 15 miles, 90 minutes to two hours, at 75 to 80 percent of maximum heart rate. Coach Kevin Beck puts it this way: "The utility of the medium-long run lies in its addressing several components of endurance at once" (Active.com). The rest is classic periodization: lactate threshold work early, VO2max intervals closer to the race, tune-up races along the way (review of the plans). The book is also blunt about monotony: stacking one moderately hard day after another carries more risk than alternating hard, easy and rest days (4th edition excerpt).

Hansons: cumulative fatigue across six days

Brothers Keith and Kevin Hanson founded the Hansons-Brooks Distance Project in Michigan in 1999, the group that produced Des Linden, the 2018 Boston Marathon champion (Wikipedia). Luke Humphrey, an athlete and coach with the group, turned the method into a book whose second edition (VeloPress, 2016) drops "two old-fashioned running traditions that often injure and discourage runners": very long runs and high-mileage weekends (publisher description).

Cumulative fatigue is the idea holding it together. Humphrey defines it as fatigue that comes "from the culmination of training and not from one specific aspect," built on four pillars: balance, moderate to high mileage, consistency and active recovery (Luke Humphrey Running). In practice, no day is brutal, but no easy day is easy enough for you to arrive fresh at the next workout. The advanced plan runs six days a week, with a strength workout on Tuesday, a tempo on Thursday and a 16-mile long run on Sunday (book excerpt at Outside).

The long run: 22, 20 or 16 miles?

This is the difference that settles most decisions, and the reasoning behind each number matters more than the number. A refresher on what the long run actually trains helps before comparing.

Pfitzinger defends the traditional long run. In the 55-to-70-mile plans, Sunday long runs start at 15 miles and peak at 22, nearly all at "endurance pace," a notch between easy and marathon pace. A few carry long race-pace blocks, such as 18 miles with 10 at marathon pace (review of the plans). In our Pfitzinger 18/55 Marathon, the longest run is 20 miles (32 km) and the peak week is 55 miles (88 km), spread over four or five running days.

Daniels doesn't treat the long run as a separate workout: it is the week's Q1, and it almost always has work inside it. One example from the 55-mile version: 16 miles total, with two 6-mile blocks at marathon pace separated by a mile easy. Twenty-mile runs appear only twice in the plan, and only from the 70-mile version up (review of the 2Q plan).

Hansons caps it at 16 and explains why. The long run should stay at 25 to 30 percent of weekly mileage; at 40 miles a week that means 10 to 12 miles, and a 20-miler only adds up at around 65 miles a week. The training benefit concentrates in the two-to-three-hour window, after which muscle breakdown outweighs the gain, which is why the book advises runners slower than 9:00 per mile (about 5:35/km) to skip the 20-miler altogether. The line that sums up the method: it's not like running the first 16 miles of the marathon, "but the last 16 miles!" (book excerpt at Outside). Humphrey insists that "it's not the 16 miles that is the magic number and it's not 20 miles": what matters is the share of weekly volume and the time on your feet (Luke Humphrey Running).

The key workouts in each method

Daniels: T and M inside long sessions

Both Q sessions in the 2Q are long by design, typically 13 to 17 miles each. Q1 is usually a long run with marathon-pace or threshold blocks. Q2 is a medium-long run with threshold work, for example cruise intervals of 3, 2 and 1 miles at T pace with two to three minutes of jogging between them. An I- or R-pace workout comes in every couple of weeks to keep some top-end speed (review of the 2Q plan). Every segment has a defined pace, and a 17-mile workout with five pace changes needs a watch.

Pfitzinger: threshold, medium-long runs and tune-up races

A typical week has one hard workout, rarely two. Early in the plan, lactate threshold runs (one example: 9 miles with 5 at threshold pace); closer to the race, VO2max intervals. Around them sit the medium-long run, the long run, recovery runs and "general aerobic" runs, plus 100 m strides and three tune-up races in the final weeks (review of the plans). The most common criticism comes from coach Jeff Gaudette: across the whole plan you run about 44 miles at marathon pace, roughly 4 percent of total mileage, and the VO2max emphasis grows just as the race approaches (RunnersConnect).

Hansons: speed, strength and tempo

The three "SOS" (Something of Substance) workouts come with exact recipes. Speed: repeats of 400 to 1,600 m at 5K-to-10K pace with a 400 m jog, volume scaled to weekly mileage (Luke Humphrey Running). Strength: work at marathon pace minus 10 seconds per mile, in sets such as 6 × 1 mile, 4 × 1.5 miles or 3 × 2 miles, about 6 miles of work for runners at 40 to 60 miles a week (Luke Humphrey Running). Tempo: a run at goal marathon pace that starts at 5 to 6 miles and grows to 10 miles over the final weeks, 12 to 14 miles total for advanced runners at peak, close to 90 minutes (book excerpt at Outside). The tempo is the most race-specific workout in any of the three methods, which is why the goal time has to be realistic from week one.

Mileage: what each method asks for

Pfitzinger selects the plan by mileage, and the book organizes its chapters that way: up to 55, 55 to 70, 70 to 85 and more than 85 miles a week (Human Kinetics). There is no version below that, and the 55-mile plan already opens at about 33 miles a week.

Daniels scales by peak mileage too, but runners who have followed the 2Q observe that it "starts to work" around 55 miles a week and is at its best near 70. The reason is arithmetic: two sessions of 13 to 17 miles eat half of a smaller week (review of the 2Q plan). Our Daniels plans, Intermediate and Advanced, run 24 weeks and open with a base phase before the specific work.

Hansons aims at the typical runner: Humphrey says the majority of people following the programs run between 30 and 60 miles a week (Luke Humphrey Running). Our two Hansons plans, the Hansons Marathon Method and the Advanced version, run 18 weeks and six days, peak at 57 and 60 miles (92 and 96 km), and keep the long run at 16 miles.

Where each method makes you pay

Daniels charges you in midweek time and attention. The 13-to-17-mile Q2 lands on a Wednesday or Thursday, and a workout with five or six different paces takes planning. Anyone who wants a plan that says what to do each day won't find it here, and anyone running under 55 miles a week is left with little room for the rest of the training (review of the 2Q plan).

Pfitzinger charges you in rigidity and weekends. Mileage jumps between weeks are quick, the structure is hard to reshuffle when life interferes, and Sunday means two and a half to three hours of running (review of the plans). Gaudette's critique about the small share of marathon-pace mileage matters most for aggressive goals (RunnersConnect).

Hansons charges you in recovery. Running on residual fatigue is the point, and for older or injury-prone runners that "running-on-tired-legs tenet is a major drawback and risk," in Marathon Handbook's assessment (Marathon Handbook). There is a structural criticism as well: workouts are set from goal pace rather than current fitness. A runner aiming for 3:10 who is currently fit for 3:20 turns the tempo into a threshold run and spends the whole plan without training at the aerobic pace that would actually fit (RunnersConnect). Being honest about your injury history matters more here than in the other two methods.

How to choose

The right question isn't "which method is best" but "which constraint can't I change over the next 18 weeks." Before deciding, review what changes when you train for a marathon compared with shorter distances.

Your Sundays are open and you want a fixed script. Pfitzinger. If you run 35 to 45 miles a week today, start with the 18/55; if you're already at 55 to 60, the Pfitzinger 18/70. With fewer than 18 weeks, the Pfitzinger 12/55 exists for runners who already have a base.

You want to decide where the mileage goes and already run 55 miles or more. Daniels. The 2Q gives you two sessions a week and total freedom with the rest, and deriving paces from a recent race keeps you from training for the time you want instead of the fitness you have.

You can run six days but can't spare three hours for a long run. Hansons. It's also the most direct route for a first marathon with a time goal when you already have a half-marathon base: the weekly tempo at race pace teaches marathon pacing better than any other workout here.

None of them fits. If you train four days a week, none of the three books was designed for you: Pfitzinger's 18/55 gets down to five days, Daniels needs the remaining mileage to exist, Hansons depends on all six. Seiler's polarized approach, below, a four-day adaptation such as the Daniels Marathon – Intermediate, 4 Days plan, or a plan filtered by available days in the plan finder are more honest starting points.

If you're still torn, goal times help calibrate: a sub-3:30 marathon usually requires the mileage that makes Pfitzinger and Daniels work; a sub-4 marathon with six available days is natural Hansons territory.

What about Seiler's polarized training?

Physiologist Stephen Seiler didn't write a marathon method. He described how elite endurance athletes distribute intensity: about 80 percent of sessions at low intensity (around 2 mmol of blood lactate) and 20 percent at high intensity, with little time in between (Seiler, 2010, IJSPP). The polarized model, formalized with Tønnessen, means "combining large volumes of low-intensity training with careful use of high-intensity interval training" (Seiler and Tønnessen, 2009).

For the marathon, polarized training is a distribution principle rather than a calendar, which is why it works as a fourth option when the three methods above ask for more days or more mileage than you have. Our 16-week polarized marathon plan concentrates the work into three sessions a week. The 80/20 training guide explains how to apply the rule.

Frequently asked questions

Can I follow Pfitzinger with the Hansons 16-mile long run?

You can, and Humphrey supplies the ruler: keep the long run at 25 to 30 percent of weekly mileage and within two to three hours. On an 18/55 peaking at 55 miles, that gives 14 to 16 miles, below the plan's 20 to 22. What you can't import is the short long run without the rest of the Hansons logic: the 16-miler works because it follows a Thursday tempo and easy days that aren't all that easy. With two rest days a week, as in the 18/55, the shorter long run just becomes a plan with less stimulus.

Which method suits a first marathon with a time goal?

Hansons, if you can run six days and already have a half-marathon base; the weekly tempo at race pace is the best pacing school of the three. Daniels, if you already run 55 miles or more and prefer autonomy: the most-cited review of the 2Q calls it "a good choice for first time marathoners who are already experienced runners." Pfitzinger assumes you have run a marathon before or have trained at high mileage for a while.

Do I need a GPS watch for these plans?

For Daniels and Hansons, in practice yes. A Daniels Q2 with a warm-up, three threshold blocks and timed jogs, or a Hansons strength workout at marathon pace minus 10 seconds per mile, is hard to execute by feel. The plans here are sent to your Garmin with every step and pace programmed, which removes the need to memorize the workout.
