Perfect for: An all-natural stamina boost.
Who knew, that root vegetable more commonly found in posh roasts (and even posher smoothies) is your bona fide secret weapon in a distance race. Studies show the nitrates in beetroot juice help your muscles use oxygen more efficiently, meaning you can go harder for longer //and// reduce those nasty post-run aches. For best results, neck up to 500ml, three hours before a race. Then brace yourself for pink-ish pee.
