Please see specific promotion Terms & Conditions for details BFPO Addresses We do ship to BFPO addresses (with Royal Mail) but for active combat zones there is a strict 2kg weight limit (as with all deliveries to BFPO addresses), so please take this into account when ordering. As a guide, with careful packaging we can just get away with a 1.6kg tub. All orders under this weight limit will be treated as standard UK orders. All orders over this weight will be priced incrementally according to their weight (£5 per 2kg increase). If you have any queries regarding a BFPO address, please contact our Customer Service Team who will be happy to assist with your order.
FUELLING THE MARATHON
Despite the well established and scientifically proven benefits of fuelling, nutrition remains one of the biggest things that marathon runners get wrong. Fuelling can be the difference between a good race and a great race, and can be the key to unlocking your true performance potential.
BETA FUEL ENERGY GEL
A dual-source energy gel, containing 40g of carbohydrate
BETA FUEL ENERGY GEL + NOOTROPICS
Delivers energy and boosts cognitive function for endurance athletes
ELITE RUNNING BOTTLE
Designed to be easy and effortless to carry while you run
HYDRO+
A convenient electrolyte drink mix designed for performance hydration
- Vitamin B1 & B2 contribute to carbohydrate conversion
- Vitamin B6 aids protein metabolism.


CARBOHYDRATE LOADING FOR A MARATHON
Our body can store around 500 grams of carbohydrate, it is essential that we complete two days of a carbohydrate loading diet to increase our muscle glycogen stores before the race. This consists of low fibre foods and a significant portion of carbohydrate, in the form of carbohydrate drinks and snacks.
It is recommended to consume a total daily carbohydrate intake of 10-12 g/kg body mass for two days before.
THE PRE RACE MEAL
The pre-race meal goal is to top up your liver glycogen stores. This meal comprises of easily digestible and low fibre solids and fluids, containing around 2-3 g/kg body mass and should be consumed at least 2.5-3 hours before the start of the race.
Runners often make the mistake of over-eating at the pre-race meal and also consume this meal too close to the race.

TRAINING WITH NUTRITION
Alongside training, nutrition plays a key role in optimising performance during marathon training by fuelling your body for intense workouts, enhancing recovery and promoting training adaptations. Nutrition remains one of the biggest things that marathoners get wrong, drastically reducing the progress made during their training programme.
6. Vitamin C contributes to normal energy-yielding metabolism.
7. Vitamin B6 & B12 contribute to the reduction of tiredness and fatigue.
EASY RUNS
Help build aerobic base, playing an important role in your ability to run long distances


EASY RUNS
Easy Runs help you build aerobic base, which plays an important role in your ability to run long distances. These are usually completed twice per week, and you should run between 8-10 km as part of these sessions.
- Pre-run, you should aim to consume a meal containing 1.5 g/kg body mass of slowly digestible carbohydrate around 2.5-3 hours in advance.
- Consume ~20 g of protein as part of the pre-training meal.
- Given the reduced intensity and duration of these runs (~1h), there is no additional need for carbohydrate consumption during the run.
- Focus on consuming 500-600 ml of water per hour and you can include electrolytes to support hydration.
- Post-run, it is important that you start consuming a mix of carbohydrate and protein early to re-store your energy stores (glycogen) and repair your muscle.
TEMPO RUNS
Key for building your body’s ability to run faster for longer


TEMPO RUNS
- Pre-run, you should aim to consume a meal containing 2 g/kg body mass of easily digestible carbohydrate around 3 hours in advance.
- Consume ~20 g of protein as part of the pre-training meal.
- Given the increased intensity and duration of these runs (~1h), you should aim to consume 30-60 g of carbohydrate per hour during the run.
- Focus on consuming 500-600 ml of water per hour.
- Post-run, it is important that you start consuming a mix of carbohydrate and protein early to re-store your energy stores (glycogen) and repair your muscle.
SPEED SESSIONS
Crucial for improving a range of physiological characteristics


SPEED SESSIONS
Speed Runs are crucial for improving a range of physiological characteristics, including your speed, power, strength and running economy.
- Pre-run, you should aim to consume a meal containing 2g/kg body mass of easily digestible carbohydrate around 3 hours in advance.
- Consume ~20 g of protein as part of the pre-training meal. Given the duration of these runs, you should aim to consume 60 g of carbohydrate per hour.
- Focus on consuming 500-600 ml of water per hour.
- Post-run, it is important that you start consuming a mix of carbohydrate and protein early to re-store your energy stores (glycogen) and repair your muscle.
LONG RUNS
Important for building your endurance capacity


LONG RUNS
- On the day of the Long Run, you should aim to consume a meal containing 3 g/kg body mass of easily digestible carbohydrate around 3 hours in advance, it is important to include fructose-rich foods or drinks (such as Beta Fuel) in your pre-run meal.
- Consume ~20 g of protein as part of the pre-training meal.
- Given the duration of these runs (> 2hours), it is recommended that during the run you consume between 60-90 g per hour of dual-source carbohydrate.
- Focus on consuming 500-600 ml of water per hour and you can include electrolytes to support hydration.
- Post-run, it is important that you consume a large serving of carbohydrate (1 g/kg body weight) and protein (20-30 g) early to re-store your energy stores (glycogen) and repair your muscle.
