Race Hydration and Nutrition

If you are going to run this distance you need a solid nutrition plan. Failure to adequately address your nutrition for this event will result in long and difficult day (and a VERY long week!). This is totally unnecessary if you learn what nutrition to take, how much and when. See detailed advice below….

Skratch Hydration

Skratch are our recommended hydration partner

Skratch Lab’s Hydration Sport Drink Mix was created for a simple purpose – to replace the electrolytes lost in sweat and to provide a little bit of energy when working out, without offending your palate or gut. Skratch initially created this drink because some of the world’s best athletes needed better!! Conventional sports drinks were undrinkable – too sweet, over-flavoured, and didn’t even replace what was lost in sweat – which defeated the whole purpose, like fighting thirst with more thirst.

The best athletes needed something to hydrate, something to quench their thirst, and something to help them perform better. So, with their help, Skratch reimagined sports drinks, stripping down what used to be a neon-coloured carnival to its bare essentials. In the process, they learned that simple wasn’t just better for elite athletes, it was better for everyone who works hard and sweats.

The result is a sports drink with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per litre), and only real fruit for flavour for a light and refreshing taste that you can drink all day. That’s it – less sugar, the right electrolyte profile, and real fruit. So, if you’ve never met a sports drink you wanted to take home, your luck is about to change.

Drink when thirsty. Don’t when not. Repeat as necessary. Click here for an INFOGRAPHIC that explains their process.

Water points, checkpoints and marshals

Water points will be established along the courses for all stages but may still be 20km apart so runners will definitely need to carry water with you whilst on the trail. These water points will be manned and will double as emergency access points with marshals with radios and / or satellite phones.

Water points will have drums of water as well as Skratch Hydration Sports Drink that allow you to refill your bladders / bottles.

There will be other basic food at water points that includes fruit cake, lollies, bananas and oranges – so we encourage you to be pretty self-sufficient for nutrition to get you from the start to the finish.

Finish line refreshments

Finish lines will have some fruit, lollies, water and nutrition drink provided by us, whilst most finish lines also have a café that allows you to purchase some food / cold drinks for yourself as listed below:

  • Stage 1: Finish at The Mercure
  • Stage 2: Finish at Standley Chasm – there is a shady café 100m from the finish line. The café does lunches and meals as well as plenty of cold drinks and refreshments.
  • Stage 3: Finish at Standley Chasm (again) – there is a shady café in the car park area, 500m from the finish line. The café does lunches and meals as well as plenty of cold drinks and refreshments.
  • Stage 4: Finish at the Ellery Creek Waterhole for a ‘beach party’ style celebration – we will organsie a food van + drinks for sale right beside the waterhole, making this the perfect finish line for the final stage of the event.

Nutrition And Hydration Tips To Get You Through A Long Run

Basic Nutrition Facts

Protein, fat and carbohydarte are the main components of your diet.

Protein supplies the amino acids essential for muscle development, but little energy while a mix of fat and carbohydrate fuel the working muscles during exercise.

  • Fat is relatively hard for your muscles to “burn” and it produces energy slowly.
  • Carbohydrate is easy for your muscles to “burn” and it produces energy quickly.

The ratio of fat to carbohydrate in the fuel mix changes according to how quickly you need to produce energy (e.g. how fast you want to run), your fitness level and how much carbohydrate you have remaining in your fuel tank.

During very low intensity running, a higher proportion of fat and a lower proportion of carbohydrate are used by the working muscles. During moderate and faster running such as during the long stage 1 race, carbohydrate is the main fuel used by the working muscles.

Unfortunately the amount of carbohydrate that your body can store is relatively small and it can become quickly depleted. When the body’s stores of carbohydrate start to run low, the muscles are forced to burn a less energetic fuel mix, which contains a higher proportion of fat than they would like. The more-and-more you deplete your carbohydrate reserves, the more-and-more fat will be added into the fuel mix. This increasing reliance on fat is felt as fatigue.

So maximising the amount of carbohydrate fuel you have available is the key to maximising performance in an endurance event. So to have a good race you should:

  • Ensure that your carbohydrate tank is full as possible before you start
  • Feed yourself with carbohydrate during exercise
  • Re-fuel your carbohydrate stores immediately after exercise finishes
  • Topping up your CARBOHYDRATES throughout the run

We all start with some carbohydrates in our bodies before we start and for a runner of 75kgs this would typically mean a maximum of about 450grams ‘pre-stored’ before the event. Now the maximum amount of carbohydrate that your body can absorb during endurance exercise depends on your body weight – such that we can only absorb about 1 gram of carbohydrates per kilogram of body weight per hour. (So our 75kg runner can only absorb about 75grams of carbs per hour of exercise).

Remember that although you can consume (swallow) a lot more carbohydrate than the 1 gram per kg, any excess will just sit in your stomach waiting to be absorbed which leaves you feeling full and bloated – uncomfortable!

So to ensure that you have the maximum amount of usable carbohydrates in your body during exercise you should try and consume about 1 gram of carbohydrates per kg of body weight per hour of exercise. Any less and you your energy levels could start dropping off and any more and it could sit in your stomach and you’ll feel bloated.

Just remember that your muscles empty your carbohydrate tank faster than you can fill it. As soon as you start exercise you start to empty your fuel tank and therefore make room for more to be added, so make sure you keep eating and adding fuel back into the tank right from the word go. (Don’t forget that sports drinks have carbohydrates in them as well so you can combine your hydration with your carbs intake – refer below).

So some key points are:

  • try and consume approximately 1 gram of carbohydrates per kg of body weight per hour of exercise.
  • start eating from the word go, don’t wait until you get hungry
  • eat and drink in numerous little bursts (almost continually) rather than in big binges which could leave you feeling full
  • try and plan your eating so you have some variety and are carrying enough to get you through

This eating program is just on way of trying to keep adequately nourished during the event and if it is quite different to what you have been doing up until not make sure you test it out on a few longer training running before the event.

Pre-Event Meal On The Morning Of The Race

The pre-event meal aims to top up carbohydrate reserves and fluid levels, while leaving your stomach feeling comfortable and you feeling confident. Generally, the pre-event meal should be consumed 2 to 3 hours before the run starts, so you have time to use the toilet afterwards!

There is a huge combination of foods which are suitable before exercise and it is important to experiment to find the most suitable option for you. Keep in mind the meal needs to provide both carbohydrate and fluid and ideally should be low in fat.

Some ideas for pre-event meals include:

  • Toast + banana + honey + sports drink + Cereal + low fat milk + fruit + juice
  • Spaghetti + toast + water + low fat yoghurt + fruit + cordial
  • Ham salad roll + sports drink + fruit smoothie + an sports energy bar

These meals need not be too scientific and should not vary too much from what you eat ever breakfast time. If you are going to change your pre event meal then it is worth experimenting before the race – just to make sure that what ever you eat leaves you feeling good rather than heavy and sitting on the toilet!

Carbohydrate Loading

To load or not to load? Carbohydrate loading is one aspect of sports nutrition which can create a lot of confusion among athletes. Carbohydrate loading aims to maximise muscle glycogen stores before endurance exercise. Basically, athletes exercising continuously for 90 minutes or more at a high intensity will benefit from some form of carbohydrate loading.

Carbohydrate loading is not an excuse to gorge on anything you can find – commitment is required to achieve the necessary high carbohydrate intake. Guidelines for carbohydrate loading include:

  • Reduce training load over the last 3 days before competition. During these 3 days, increase carbohydrate intake to 8-10g/kg body weight
  • Avoid the temptation to indulge in high fat foods. This may cause weight gain and will make it difficult to consume enough carbohydrate
  • Reduce fibre intake to leave room for high carbohydrate foods and avoid feeling bloated
  • Make use of compact carbohydrate sources such as sports products
  • Be careful eating too many carbohydrates the night before the race, you don’t want to stuff so much in that your body does not have enough time to process it before you start and it is just sitting there as you start running up that first hill!


Just as with nutrition and food, keeping hydrated whilst out running will ensure you perform at your best and have an enjoyable day out.

Keeping yourself well hydrated isn’t easy and for athletes the importance of staying hydrated cannot be overstated. During exercise the amount of sweat produced varies hugely from person to person according to body size, gender, exercise intensity and environmental conditions. The average sweat rate for an 80kg person cycling at a moderate intensity in 20 deg C heat is 1 litre / hour. So dehydration can occur very quickly if we are not making an effort to replenish lost fluids from BEFORE THE START!

There plenty of scientific methods to determine if you are dehydrated but the easiest guideline is to keep track of how often you have to go to the toilet! – you should be peeing every 3 hours and it should be straw coloured (not bright yellow!) so if things are different down there you should drink more!

Start drinking BEFORE THE RACE

Keeping hydrated on a daily basis needs to become a habit and especially so in the 2-3 days before the race – try the following tips:

  • Keep a filled drink bottle with you whenever you can and sip from it regularly throughout the day.
  • Keep the bottle on your desk at work or in the car or in your bag in the staff room – wherever you can access it frequently
  • Try to minimise your intake of coffee and tea. Caffeine is a diuretic, meaning that it will cause you to urinate more and therefore lose even more water
  • Likewise alcohol doesn’t count as good fluid!! It too is a diuretic
  • During a normal day even when you are not training, you should aim to get through at least 2 large bottles or 8-12 glasses of water

BEFORE THE START of a long race

  • Drink at least 400 – 600mls of water or sports drink in the 2 hours before you run.
  • Ensure that you are well prepared, fill your hydration pack and bottles are full with water or energy drink and carry plenty of food with you
  • Avoid a heavy session on the beer the night before!

DURING a long race
If it going to be hot (which is very likely) these pointers become even more important to ensure you have a safe and enjoyable day:

  • Start drinking early and whenever you feel thirsty
  • Drinking regularly in small sips is often more comfortable than taking in a larger quantity at once. Hydration packs are great for this
  • There are water points but don’t rely on these alone – you must be drinking in between these points
  • Fill your bottles up if you are running out. You will lose more time due to reduced performance if you keep running in a dehydrated state than if you spend a few minutes replenishing fluid supplies and keep drinking
  • Avoid cordials and juices before, during and immediately after running as the high sugar content can slow down stomach emptying and mean that the real fuels takes longer to reach the working muscles
  • Sports drinks are absorbed quicker than water and have additional minerals in them to replace what you have lost through exercise.

The main message is keep drinking and eating the right stuff from before the start and you will keep going, enjoy your event and recover faster.
