TL;DR: The TCS Sydney Marathon is on Sunday 30 August 2026, which puts most runners right in the middle of peak training load. This is exactly when niggles turn up, and exactly when they get ignored. A true niggle settles within 24 to 48 hours and doesn’t change the way you run. Anything that lingers, worsens, or alters your gait needs a proper look before it turns into a DNS. Book in with your physio if in doubt.
If you’ve picked up an ache in the last week or two and you’re wondering whether to keep running on it, here’s the short answer: if it eases within a day or two of rest, doesn’t get worse session to session, and hasn’t changed how you’re moving, it’s likely a normal training niggle. If it’s still there after 48 hours, gets sharper as you warm up rather than easing off, or you’ve noticed yourself favouring one side, that’s your cue to get it assessed rather than hope it settles on its own.
Why the six-week mark is when things start to surface
Six to eight weeks out from a marathon is typically the heaviest block of training most runners will do all year. Long runs are at their longest, weekly kilometres are near their peak, and there’s often a long run or two with race-pace kilometres built in. Tissue that’s coped fine with lower volume for months can start complaining once that load stacks up week after week without much recovery in between.
This is also the point where taper is still a few weeks away, so there’s a temptation to push through discomfort because “the big sessions are almost done.” That’s the exact window where a manageable niggle, left unmanaged, becomes an injury that costs someone their start line.
Niggle vs injury: a quick checklist
A niggle is more likely if:
- It settles within 24 to 48 hours of rest or reduced load
- It doesn’t get worse from one run to the next
- It doesn’t change your stride, posture, or pace
- Pain sits around 2 to 3 out of 10 and doesn’t spike sharply
It’s more likely to be an injury if:
- It’s still there, or worse, after two days
- It builds through a run rather than warming out of it
- You’re changing how you run to avoid it (shortening stride, landing differently, limping)
- There’s swelling, sharp pain, or pain that wakes you at night
What to do in the first 48 hours
If something new comes up after a run, the immediate plan is straightforward: back off the load, not necessarily stop completely. Swap a hard session for an easy one, drop the volume, or take a rest day. Keep an eye on how it responds. If it settles with a couple of easier days, you’re likely fine to build back in gradually. If it doesn’t shift, or it’s affecting your form, that’s the point to get it checked rather than testing it against a 30km long run. Backing off now won’t compromise your marathon training
Common complaints we see in the lead-up to a marathon
A few patterns show up every marathon cycle:
- Calf and Achilles tightness, usually from a jump in volume or added hill or speed work
- ITB-related knee pain, often linked to fatigue changing running mechanics late in long runs
- Shin discomfort, which can range from normal muscle fatigue to something that needs load management
- Hip or glute niggles, frequently tied to reduced strength work once running volume takes priority
None of these are rare, and none of them are automatically marathon-ending. What matters is catching the pattern early and adjusting training around it rather than ignoring it and hoping race week fixes itself.
When to book in with a physio
Book an appointment if any of the following apply: the discomfort hasn’t eased in 48 hours, it’s getting worse rather than better, it’s changing how you run, or you simply don’t feel confident about what’s going on. Six weeks out is still enough time to adjust a training plan, manage a niggle properly, and get to the start line in good shape. Two weeks out, the options are far more limited. Earlier is always better here. You can easily book in here
Key takeaways
- With the marathon on 30 August 2026, most runners are now in their heaviest training block, which is when niggles are most likely to appear.
- A true niggle eases within 24 to 48 hours and doesn’t alter how you run. Anything beyond that deserves an assessment.
- Reduce load rather than stopping outright when something new comes up, then reassess after a couple of easier days.
- Calf, Achilles, ITB, shin, and hip niggles are common at this stage of a marathon block and are manageable when addressed early.
- Six weeks out gives you options. Two weeks out gives you far fewer. If in doubt, get it looked at now.
FAQ
Should I stop running completely if I feel a niggle? Not necessarily. Reducing volume or intensity for a couple of days and monitoring the response is usually the first step. Complete rest is more relevant if pain is sharp, worsening, or changing your gait.
Can I still fix an issue with six weeks to go? Yes. Six weeks is generally enough time to manage a niggle, adjust training load, and still arrive at the start line in solid shape, provided it’s addressed rather than pushed through.
What if the pain only shows up during longer runs? That’s still worth mentioning to a physio. Issues that only appear under fatigue or higher mileage are often related to how your form changes late in a run, which is something that can be assessed and worked on.
Is it normal to have some aches this close to race day? Some general muscle fatigue and tightness is expected in a heavy training block. The distinction is between normal fatigue, which settles with easy days, and pain that persists, sharpens, or changes your running pattern.
Do I need a referral to see a physio before the marathon? No referral is needed. You can book directly for an assessment.
