This sounds too good to be true !
Research at the University of Exeter’s School of Sport Health and Science shows that drinking 500 ml of fresh beetroot juice for six days can lead to an increase of up to 16% in the endurance of cyclists. Here’s a link to the University’s own summary.
It is unclear to me whether trained athletes get a similar boost in endurance and how the consumption of juice can improve training in the long term. Anyway, given that drinking beetroot juice probably has few deleterious side effects, I’ll be imbibing it in industrial quantities before my next marathon (Barcelona, in two weeks). Who knows, it may help !
