Nutrition for Ultra Marathons

Ultra Running Nutrition

Ensuring you're adequately fueled for your ultra marathon is paramount to maintaining energy levels and maximising performance, especially during endurance endeavours lasting 60 minutes or more. While traversing challenging terrain, your body utilises its glycogen stores as its primary energy source. Failing to replenish glycogen levels sufficiently can lead to fatigue, reduced concentration, and a decrease in pace.

Energy gels and drinks are indispensable for refueling during ultra marathons. Gels provide concentrated doses of carbohydrates in a convenient, easily digestible form, perfect for rapid energy boosts whilst on the move. Conversely, energy drinks offer carbohydrates in a more diluted form, ensuring a steady supply of fuel with every sip. Aim to consume between 30 to 60 grams of carbohydrates per hour from gels and/or drinks when undertaking ultra marathons lasting over 60 to 90 minutes. This refueling strategy will help maintain your endurance and keep you performing optimally amidst the demanding conditions of the trail.

To excel in ultra marathons, hydration is key both before and during your runs to maintain optimal performance and prevent dehydration. Prioritise consuming up to 500ml of fluids 2-3 hours before your run to ensure you're adequately hydrated. During lengthier ultra runs, aim for hydration intervals of 100 to 200ml every 20 to 30 minutes to replace fluids lost through sweat. While water may suffice for shorter outings, opt for hydration drinks during runs lasting over 60 minutes to replenish essential electrolytes lost through perspiration.

For effective recovery post-run, it's crucial to replenish both carbohydrates and protein, using a recovery drink within 30 to 60 minutes. Aim for a protein intake of 0.3-0.5 grams per kilogram of body weight to support muscle repair and growth. Convenient options such as recovery bars or drinks offer a swift and efficient means of refueling. By promptly replenishing your body's nutrients, you'll alleviate muscle soreness and pave the way for future ultra marathon achievements, bolstering your strength and endurance.
