@hybridtraininghealing: I’ve been doing this since day one of running — back when I was still a smoker, even smoking before and after my runs. Studies show that beetroot juice, through its nitric oxide boost, can significantly improve endurance. In fact, research has found it can reduce oxygen cost during exercise by up to 5%, which means running feels easier at the same pace. I used to hate the taste so much I’d have to hold my nose, then I switched to capsules. Now I actually love the juice — to me, it’s the taste of speed.
