Stay injury-free this summer
You've been running for a while. Maybe you've ticked off a few Parkruns, done a fun run or two, and now something bigger is calling - a half marathon, a club race, a trail event.
The leap from casual to competitive running is one of the best decisions you can make for your fitness and your mindset. But it's also one that your body needs help preparing for.
Autumn and winter are prime race seasons in New Zealand, and the difference between a great race and a painful one often comes down to what you do in the weeks before it. Here's what our physiotherapy team recommends.
The most frequent issue our physiotherapists see in runners preparing for their first competitive event isn't a lack of fitness - it's doing too much, too soon. Your cardiovascular system adapts relatively quickly to increased training load. Your tendons, bones, joints and connective tissue take considerably longer.
This mismatch is where injuries happen. Shin splints, Achilles tendinopathy, stress fractures and IT band syndrome are almost always the result of load increasing faster than the body can adapt - not bad luck.
The good news is that with a structured approach, most of these injuries are entirely preventable.
For a half marathon or similar event, a 12–16 week training plan is the minimum. If you're starting from a lower base, 18–20 weeks gives you the buffer to recover from any setbacks without compromising your race. Resist the temptation to compress your preparation — time is your most valuable training tool.
Spend the first four to six weeks of your programme running at an easy, conversational pace before you introduce any speed work, tempo runs or hills. This isn't wasted time - it's building the aerobic and structural foundation that makes harder training possible without breaking you down.
The guideline of not increasing weekly mileage by more than 10% is a useful starting point, but it's not a guarantee. More important is paying attention to how your body responds. If soreness isn't resolving between sessions, if something feels sharp or localised, or if you're waking up stiff — those are signals to ease back, not push through.
Runners who include strength training in their programmes get injured less and perform better. Focus on the lower limb and core: single-leg exercises like split squats and step-ups, calf raises, glute bridges and dead bugs. Two sessions per week of 20–30 minutes is enough to make a meaningful difference to your injury resilience.
Cold muscles are less pliable and more prone to strain. In autumn and winter conditions, spend at least 10 minutes on dynamic movement before picking up pace -leg swings, hip circles, high knees, walking lunges. Save static stretching for after your run when muscles are warm.
Fitness is built during recovery, not during training. That means prioritising sleep, eating enough to support your training load, staying well hydrated, and scheduling at least one complete rest day each week. As your event approaches, taper your training load in the final 1–2 weeks to arrive at the start line fresh rather than accumulated.
Winter running has its own demands. Layer moisture-wicking fabrics rather than a single heavy layer, wear high-visibility clothing for early morning or evening runs, and check that your footwear has adequate grip for wet or muddy conditions. Don't debut new shoes on race day - give any footwear at least 3–4 weeks of regular use before you race in it.
If you're investing months of training into an event, a physiotherapy running assessment is one of the most valuable things you can do. It analyses your gait, foot strike, cadence and movement patterns to identify risk factors before they become injuries - and can improve your efficiency so you get more out of every kilometre.
If you notice any of the following, don't wait - early physiotherapy intervention is far more effective than managing something that's become chronic:
Most running injuries do not require you to stop running entirely. A physiotherapist can modify your training load while keeping you moving and on track for your event.
