City2Surf

City2Surf is 14 kilometres, and for most people the hard part is not race morning. It is the eight weeks before it, when weekly mileage climbs and the body has to adapt without breaking down. The most common mistake is doing too much too soon, then under-fuelling and under-hydrating the long runs that are meant to build endurance. Getting your energy, hydration and recovery right across the training block is what lets you build distance gradually and arrive at the start line ready rather than worn out.

Carbohydrate is the fuel that runs low first on longer efforts. Your muscles store only a limited amount of glycogen, and once a run pushes past roughly 60 to 90 minutes, taking on carbohydrate helps maintain pace and delay fatigue. This is where energy gels and endurance fuel earn their place, giving fast-absorbing carbohydrate in a form you can take on the move. Gels that combine glucose with fructose use two separate absorption pathways, which allows a higher rate of carbohydrate to be used and tends to sit more comfortably in the gut on long runs. Some gels also include caffeine, which has solid evidence as a performance aid for endurance, best trialled in training rather than discovered on race day.

Hydration is the other lever people get wrong, usually by relying on plain water. The main thing you lose in sweat is sodium, and on a warm Sydney morning or a long run, replacing fluid without replacing sodium leaves you flat and can affect how you feel and perform. A good electrolyte formula replaces sodium alongside potassium and magnesium, and the right concentration depends on how heavily you sweat. Isotonic options suit longer, hotter efforts where you need fluid and carbohydrate together, while lighter hypotonic blends suit shorter sessions and everyday hydration. The goal through training is to find what your stomach tolerates so race day feels familiar.

Recovery is what makes the next session possible, and it is built on protein, minerals and sleep. After a long or hard run, protein supports the repair and rebuilding of muscle, and a fast-digesting, low-lactose option like whey protein isolate is an easy way to hit the 20 to 40 grams that supports that process. Magnesium plays a role in normal muscle function and energy metabolism and is often used through a heavy training block to support recovery and sleep quality, the time when most repair actually happens. For runners ramping up mileage, paying attention to muscle recovery between sessions is what protects against the niggles that derail a training plan.

Everyone sweats, fuels and recovers differently, and the fastest way to get yours right is to ask someone who does this for a living. Our practitioners offer free in-store consultations where they can help you work out your sweat rate, practise your fuelling, and build a hydration and recovery plan that fits your training and race-day goals. If you are new to running or managing a health condition, this is the place to start. You can book time with our practitioner team before your next long run.
