==Implications for Runners==
Beetroot supplementation is the only known way of reducing the energy cost of exercise(improved [[Running Economy]]). This reduction in energy cost is especially important for marathon runners, where the carbohydrate [[Glycogen]] stores are a limiting factor in performance. Runners focused on shorter distances would benefit from the increased time to exhaustion at high intensity.
==Period of Effect==
The changes from beetroot take effect in about 30 minutes, peak after 90 minutes, stay elevated for 6 hours<ref name="Spitting"/> and remain effective for at least 15 days<ref name="Time"/> Taking beetroot juice daily will build up the effect over a 3-4 days then plateau.
