Nutrition
: "I'm trying to make fuelling for endurance more affordable, all whilst reducing single-use plastic waste we create in our sport and hobby - I created DirtBags which are just 2 days away from launching which are an alternative to single-use energy gel, powder and chew packets that cost way too much!"
