Comrades Marathon is a name that is known around the world as a test of pure grit and a celebration of perseverance and comradery. We embrace the long road, not knowing how the day will end. One thing we know is that if we fuel right, you can eliminate a number of risks that are inherent with running 89km on tar. We have designed a race pack for the Comrades Marathon with the most optimal combination of Maurten products to help you get the the finish line. It works on the basis of +/-70g of Carbohydrates on average per hour for a 9 hour run which totals 660g of carbs for the duration of your run. The fuel plan includes the pre fueling as suggested for the days preceding Comrades and post race carbohydrate recovery fuel.
The following two tips are suggestions. Discuss with your coach for more detailed advice.
For optimum race week preparations, we advise that you hydrate to thirst in the week of the race, with an electrolyte drink to prevent over hydration. Ensuring that you arrive on race day with elevated/optimum levels of electrolytes is going to do you better than trying to maintain your electrolytes on the day of Comrades. Running within your ability will ensure that you don’t exert muscles, beyond their capacity. Over exertion can lead to muscle cramps or spasms, due to physiological or energy deficits. Fueling early will ensure that your muscle glycogen isn’t used to power your running. Maurten allows a higher and faster uptake of carbohydrates during exercise, meaning that the fuel you put in, can be used, as you are consuming it, thereby saving the muscle glycogen, and reducing the risk of muscle cramp and spasm. Knowing how much fuel to put in per hour is key to ensuring you are keeping your carbohydrate intake at the correct grams per hour. During your training long runs, you would have worked out this key element of fueling. If you are aiming to take in 70gram per hour, then you would ideally be consuming 70grams per hour in your training runs. Your training runs are as much about endurance and speed as they are about getting used to the carbohydrate intake. The day before Comrades, it’s advisable to increase your carbohydrate intake to between 10g – 12g per kg of body weight. If you are 70kg, you would multiply your weight by 10g, Eg 70 x 10g = 700g of carbohydrates. Rice, oats, potatoes and pasta are your easiest meals to prepare as carbohydrate rich foods. You can supplement your carbohydrate intake with Maurten drink mix, which will also tick off the hydration box.
If you are running a 7 hour Comrades your average carbohydrate intake will be 82g per hour, a 9 hour Comrades will bring your carbohydrate intake down to 64g per hour and an 11 hour comrades will mean 52g of carbohydrates per hour.
Our race plan for Comrades is based on using Maurten for the entire day, with only small deviations when you feel you need something ‘different’. Drink water to thirst. Consume salted potatoes and/or bananas as you would normally. Our plan includes caffeine gels which are in aid of reducing the feeling of fatigue. There are two strategies for taking in caffeine to aid ultra distance endurance events, starting early, and alternating a non caffeine gel with a caffeine gel every feed, or starting halfway and maintaining caffeine to the end.
