Marathon training Sydney runners undertake each year requires more than simply increasing weekly kilometres. Whether you are preparing for the Sydney Marathon 2026, the City2Surf, or your first marathon, following a structured marathon training plan and focusing on marathon injury prevention can significantly reduce your risk of running injuries. At BeFit Training Physiotherapy, our team provides expert marathon physiotherapy, running assessment and evidence-based rehabilitation to help runners across Sydney train consistently and arrive at race day healthy and confident.
The Most Important Thing Runners Get Wrong
They increase their mileage too fast.
Marathon training demands patience. Your cardiovascular system adapts to training load within days. Your tendons, bones, and connective tissue take weeks, sometimes months. This gap is where most overuse injuries are born. A runner can feel fit and energetic at week six of their programme and still be accumulating stress in tissues that are not yet ready for the load they are carrying.
The commonly cited 10 percent rule, increasing weekly volume by no more than 10 percent each week, is a useful starting point. But context matters. A runner coming off a base of 30km per week can handle different increases than someone returning from a two-month break. What does not change is the principle: build more slowly than your motivation wants you to.
How a Smart Marathon Block Is Structured
Most beginner to intermediate marathon programmes span 16 to 20 weeks. Here is what each phase is designed to do.
Weeks 1 to 6 — Base Phase
Build mileage gradually. The majority of runs should be easy, comfortable enough to hold a conversation. Introduce strength training two to three times per week. This phase feels unremarkable by design. The work being done is structural.
Weeks 7 to 14 — Build Phase
Long runs extend progressively. One quality session per week is introduced, typically tempo efforts or structured interval work. Strength training continues. This is the phase where overuse injuries most commonly appear, because load is climbing while fatigue is accumulating.
Weeks 15 to 17 — Peak Phase
Your biggest weeks. Long runs reach their maximum distance, typically 32 to 35km. Most training plans do not recommend running the full 42.2km in training. Recovery between sessions is critical. Sleep and nutrition are no longer optional considerations.
Weeks 18 to 20 — Taper Phase
Weekly volume drops significantly. Intensity is maintained, but total load reduces. Many runners feel sluggish or anxious during taper, this is a normal physiological response. The body is consolidating weeks of training. Trust it.
The Injuries That End Marathon Campaigns Early
The most common running-related conditions we see in clinic are largely preventable, or at minimum manageable when caught early. If any of these sound familiar, a running assessment can identify what is driving the issue and what to do about it.
Runner’s Knee (Patellofemoral Pain)
A dull ache around or behind the kneecap, typically worst on stairs, hills, or after sitting for long periods. Usually driven by a combination of training load, hip and glute weakness, and running mechanics. Responds well to load management and a structured strengthening programme.
IT Band Syndrome
A sharp, lateral knee pain that tends to appear at a predictable distance into each run, often around 20 to 30 minutes, then eases with rest, until it does not. IT band issues rarely resolve with stretching alone. Load management, hip strength, and occasionally gait retraining are the real levers.
Bone Stress Injury
A localised, pinpoint ache in the shin, foot, or hip that worsens with activity and eases with rest. Bone stress injuries exist on a spectrum from mild stress reaction to stress fracture. If a specific spot is not improving after a few days off, it warrants proper assessment. Running through bone stress injury carries real risk of a full fracture.
Plantar Fasciopathy
The sharp heel pain most noticeable first thing in the morning or after periods of rest. Common when runners have increased mileage quickly or changed footwear. Most cases respond well to a graduated loading programme targeting the plantar fascia and foot intrinsic muscles.
Achilles Tendinopathy
A stiffness and aching in the Achilles tendon, typically at the back of the heel or mid-tendon. Often worst in the first few steps of the morning, then easing with movement before returning after a hard session. Tendinopathy responds to structured loading, not rest alone, but the loading needs to be progressive and individualised.
Why Strength Training Is Not Optional
Running is often seen as the whole job. It is not.
Strength training for runners builds the capacity to absorb force, maintain form when fatigued, and reduce the risk of overuse injury. The structures most commonly injured in marathon runners, tendons, bones, joint cartilage, respond to progressive resistance loading in ways that running volume alone cannot replicate.
The exercises that matter most for runners are not complicated. Single-leg squats, Romanian deadlifts, calf raises, hip abductor work, and basic core stability training cover the majority of what a marathon runner needs. The key is that they are done consistently and progressed appropriately throughout the training block, not dropped when mileage climbs.
Our physiotherapists combine clinical expertise with a strength and conditioning background, which means the strength work we recommend is built around your training load and your goals, not a generic template. Every programme starts with an individual assessment.
The Role of Recovery in Marathon Training
Recovery is not the absence of training. It is training.
The physiological adaptations that make you a faster, more resilient runner happen during recovery, when the body rebuilds and strengthens the tissues that training has stressed. Runners who skip recovery or treat easy days as moderate days accumulate fatigue without accumulating fitness.
Practical recovery strategies that are evidence-supported include adequate sleep, protein intake distributed across the day, managing life stress where possible, and genuine easy-effort running on recovery days.
Sydney’s Upcoming Races Worth Training For
Sydney’s 2026 running calendar gives runners at every level a goal worth working toward. Two of the biggest events are right on the Eastern Suburbs doorstep.
Voltaren City2Surf — 9 August 2026
The world’s largest fun run, drawing more than 80,000 participants each year. The iconic 14km course winds from Hyde Park in the CBD, over Heartbreak Hill, and finishes at Bondi Beach, right in BeFit’s backyard. Whether you are chasing a personal best or ticking a bucket-list event, City2Surf is the perfect mid-year goal for Eastern Suburbs runners and a great foundation race for anyone building toward the Sydney Marathon three weeks later.
TCS Sydney Marathon presented by ASICS — 30 August 2026
The seventh Abbott World Marathon Major and the largest marathon ever held in Australia, with more than 33,000 finishers in 2025. The course runs from North Sydney, across the Sydney Harbour Bridge, and finishes at the Sydney Opera House. Check the official TCS Sydney Marathon website for 2026 ballot and entry details.
When to See a Physio During Marathon Training
You do not need to be injured to benefit from seeing a physiotherapist during a marathon campaign. A running assessment early in your training block can identify movement patterns, strength imbalances, or load tolerance issues before they become injuries. For runners with a history of recurring problems, knee pain, Achilles issues, IT band syndrome, this kind of proactive assessment is particularly valuable.
If something has been niggling for more than a week and is not settling with a day or two of reduced load, that is the right time to come in. The earlier an issue is addressed, the less disruption it causes to training. Our physiotherapists at both the Edgecliff and Coogee clinics work regularly with runners at all levels, from first-time City2Surf participants to experienced competitors preparing for the Sydney Marathon.
Frequently Asked Questions
How far should my longest run be before a marathon?
Most training plans cap the long run at 32 to 35km, two to three weeks before race day. Running the full 42.2km in training is generally not recommended, the recovery cost is high and the benefit over a well-executed 35km long run is minimal.
How do I know if a niggle is serious enough to rest?
If a pain or discomfort is a 3 out of 10 or below, does not worsen during a run, and resolves within an hour of finishing, it may be manageable with modified training. If pain is higher than a 3 out of 10, worsens during a run, or does not settle within 24 hours, reduce load and seek assessment. Pain localised to a specific spot on bone, particularly in the shin, foot, or hip, should always be assessed.
Should I do strength training right up until race day?
Reduce the intensity and volume of strength training during your taper, the final two to three weeks before the race, but do not stop entirely. Maintaining movement patterns helps with race-day readiness. Avoid heavy loading in the final week.
Do I need a referral to see a physio at BeFit?
No referral is required. You can book directly through our website at either the Edgecliff or Coogee clinic.
Can a running assessment help even if I am not injured?
Yes. A running assessment looks at your movement mechanics, foot strike pattern, cadence, and hip and trunk control. It can identify inefficiencies or asymmetries that increase injury risk over high mileage, before they become a problem.
What is the difference between a running assessment and a general physio appointment?
A general physiotherapy appointment focuses on assessing and managing a specific injury or complaint. A running assessment is a proactive analysis of how you run, using observation, video analysis, and movement screening, to identify what might be limiting your performance or increasing your injury risk. Both are available at BeFit.
