There is strong evidence suggesting that protein intake during exercise will reduce subsequent muscle soreness and assist future performance, so in ultra or multi-day events this can become beneficial. Additionally, protein can be used as an energy source at the lower intensities we typically operate at during an ultra distance event, be it running, cycling or multi-sport. The protein in Sparta comes from a variety of natural sources, many of which also offer some carbohydrates. We’ve used oat flour, chia flour, chickpea flour and rice protein to give a healthy balance as well as a hearty, savoury taste.

Leucine, one of the three BCAAs (branch chain amino acids) has been shown to preserve glycogen stores, reduce fatigue, reduce muscle damage which can occur during long-distance/ultra events. L-Glutamine is an essential amino acid with important role in immunity. Glutamine levels normally become depleted during exercise which can reduces immune response and allows and increase in fatigue markers in the body. Glutamine supplementation improves those fatigue markers, reduces the usual exercise-related drop in L-Glutamine and may reduce immune cell damage. Obviously supporting the immune system is very important for prolonged or multi-day performance and helps you stay strong day after day.

The key carbohydrate source is isomaltulose which has half the sweetness of sucrose but still offers the energy associated with carbohydrates. With a lower GI (glycaemic index) this slower release energy source avoids the sugar spike ,and subsequent crash, from simple sugars and gives more sustained energy source for muscles and brain.
