Most runners preparing for a fall marathon are logging 60 to 80 kilometers a week and feeling the strain. French marathon runner Manon Trapp is doing more than twice that. With the Berlin Marathon in her sights and a personal best on the line, Trapp's preparation offers one of the clearest windows available into what elite-level marathon training actually looks like in practice.
It's not just the volume that's striking. It's the architecture behind it.
What 180km Weeks Actually Look Like
Trapp's peak training blocks exceed 180 kilometers per week, a figure that places her among the upper tier of competitive female marathon runners globally. To put that in perspective, that's roughly 112 miles per week sustained across multiple consecutive weeks, not as a one-off spike.
At that volume, running twice a day becomes the norm rather than the exception. A typical day might include a 90-minute aerobic run in the morning followed by a quality session in the afternoon: tempo intervals, marathon-pace efforts, or a fartlek depending on where she is in the training cycle. Easy days are genuinely easy, kept at conversational pace to protect recovery capacity.
The key structural principle behind her training is progressive overload with deliberate recovery. Volume builds across three to four weeks before dropping sharply in a recovery week. That pattern repeats throughout the 16 to 20-week build. It's a format that exercise physiologists consistently identify as optimal for aerobic adaptation without accumulating excessive fatigue.
For context on what elite training demands at this level, the injury toll across professional distance running is significant. Even seasoned athletes are not immune, as Faith Kipyegon's withdrawal from the rest of the 2026 season demonstrates. Longevity at the top requires as much precision in recovery as in training load.
Altitude Camps: The Aerobic Edge
Altitude training is one of the most evidence-backed performance tools available to endurance athletes. Trapp's Berlin prep includes structured altitude camps, typically conducted at elevations between 2,000 and 2,400 meters above sea level. At those heights, reduced oxygen availability triggers a cascade of physiological adaptations: increased erythropoietin production, higher red blood cell mass, and improved oxygen-carrying capacity.
The performance gains from a well-executed altitude block are real. Research consistently shows that three to four weeks at moderate altitude, followed by a two-to-three-week sea-level return before competition, can meaningfully improve VO2 max and lactate threshold. Both matter enormously when you're targeting a specific marathon time.
Popular altitude training destinations among European elites include Font Romeu in the French Pyrenees, Iten in Kenya, and St. Moritz in Switzerland. These locations aren't just high. They offer the infrastructure, terrain variety, and coaching access that serious athletes need to train effectively at reduced oxygen levels.
The financial reality is worth acknowledging. A serious altitude camp, including travel, accommodation, and coaching support, can run $3,000 to $6,000 or more for a three-to-four-week block. That's the elite version. But the physiological principle doesn't have to cost that much to apply partially.
What Ambitious Amateur Runners Can Actually Take From This
You're not running 180 kilometers a week. You don't need to. But the strategic logic behind Trapp's preparation translates directly to ambitious amateur runners targeting a fall marathon personal best.
Here are the principles worth adapting:
- Progressive volume with structured recovery weeks. Build your weekly mileage for three weeks, then cut back by 20 to 30 percent in week four. Don't skip the down weeks. That's where the adaptation from the previous block actually consolidates. Compressing this process is one of the most common mistakes recreational runners make.
- Polarized intensity distribution. Elite programs spend roughly 80 percent of total training volume at low intensity and 20 percent at high intensity. If most of your runs feel moderately hard, you're probably training in the gray zone that's too fast to maximize aerobic base and too slow to build real speed. Run your easy days easier and your hard days genuinely hard.
- Altitude exposure alternatives. If a full altitude camp isn't realistic, altitude tents are available to rent or purchase, typically running $500 to $1,200 for a quality sleeping tent setup. Sleeping at simulated altitude for four to six weeks can produce measurable hematological adaptations. It's not identical to living and training at altitude, but it's a credible middle ground for serious amateurs.
- Race-specific marathon-pace work. A common training error is never running at goal marathon pace until race day. Trapp's program incorporates long tempo efforts and marathon-pace segments embedded in long runs. Start incorporating goal-pace miles into your longer runs from week eight onward in a standard 16-week build.
- Peak week, not peak day. The highest mileage week in a well-structured plan typically falls three to four weeks before race day, not the week before. The final three weeks are a taper, not an extension of your build. Respecting the taper is something many runners intellectually accept but emotionally resist.
If you're working through the fundamentals of a first or second marathon build, the training principles that actually matter for first-time marathoners are a useful complement to what elite preparation reveals at the top end.
The Mental Architecture of a Long Build
One element of elite preparation that rarely gets the coverage it deserves is the psychological structure required to sustain a 20-week training block at high volume. Trapp's preparation isn't just physically demanding. It requires a consistent capacity to manage fatigue, recalibrate expectations mid-block, and stay focused on a goal that's still months away.
The mental load of long training builds is real and often underestimated by recreational runners. Hard days feel worse when accumulated fatigue is high. Easy days can feel psychologically deflating when you feel slow. Long runs in poor conditions test commitment in a way that race day rarely does, because there's no crowd and no adrenaline to carry you through.
Developing a set of mental strategies specifically for long runs and training blocks is a genuine performance lever. The mental approaches that get experienced runners through long runs and tough races are worth studying before your build gets deep into its hardest weeks.
Nutrition at Elite Volume: A Practical Frame
Running 180 kilometers a week creates an enormous caloric and micronutrient demand. Trapp's daily nutrition is calibrated to support that output while maintaining body composition appropriate for marathon performance. That means high carbohydrate availability around key sessions, adequate protein to support muscle repair, and careful attention to micronutrients that heavy training can deplete.
Iron is the most critical nutrient for endurance runners. Ferritin levels drop under high training loads, particularly for female athletes, and even sub-clinical iron deficiency without anemia can measurably impair aerobic performance. Zinc, magnesium, and B vitamins also come under pressure during sustained heavy training.
Gut health is an often-overlooked factor at high training loads. Intense running is physiologically stressful to the gastrointestinal system, and GI distress during races is a performance limiter for many marathoners. The relationship between training load, gut microbiome composition, and race-day digestion is an active area of research. If you're working through a serious marathon build, what you know about how to choose a probiotic that actually delivers results is worth considering as part of your nutrition protocol.
Supplement quality matters enormously when you're relying on specific micronutrients to support heavy training. The gap between label claims and actual product content is wider than most athletes realize, which makes understanding how to evaluate what you're taking a practical skill, not just a consumer concern.
What Berlin Tells Us About the Sport
Berlin is one of the fastest marathon courses in the world and a consistent venue for world records and personal bests. The flat profile, typically cool September temperatures, and deep competitive field make it an ideal setting for time-focused performances. Trapp's targeting of a personal best there is a deliberate choice, not an accident of scheduling.
The broader amateur racing ecosystem is also evolving. While events like Berlin represent the pinnacle of road racing, local trail races are reshaping how community-level runners engage with the sport, offering a more accessible and often more sustainable on-ramp to serious competition.
But for the runners whose goal is a fast road marathon, there's still no substitute for understanding how the best in the sport prepare. Trapp's 180-kilometer weeks, her structured altitude camps, her polarized intensity approach and taper discipline represent a coherent system built around a single goal: running as fast as possible on race day.
You can borrow the logic of that system without replicating the volume. Build progressively. Protect your recovery weeks. Take intensity seriously in both directions. And respect the taper. That framework, stripped of the extremes, is available to any runner willing to apply it with consistency.
