BoilerTom, Do you use beet juice and if so, did yo see any positive results?
From a discussion we had on another thread the recommendation came up to use coconut oil before long runs. I started using it and do so every morning. It is hard to say how much of a difference it made but I never had any bad long runs and a lot of those had MP miles in them.
Barney, use a good recovery drink after hard efforts. I have noticed that it has helped my recovery tremendously. I can do a 20 with 12 @ MP and feel good the next day and not drag. I use Endurox R4. Chocolate milk works well. I only use Endurox as I do a lot of my long runs on the towpath or in the Cuyahoga National Park and since I have to drive there I can keep the drink in the truck and not worry about spoilage.
It's hard to say because I make some form of juice nearly every day, but I don't use beet juice every day. Nearly daily we use spinach, and sometimes kale, which are both high in nitrates. I just thought I'd pass along a piece of info that Tinman once shared with me, while referencing one of many studies done on "beet juice and athletic performance." No matter how you look at it, eating healthy is vital.
As for evidence, a friend of mine does ultra-crazy endurance events. He's currently in Italy doing 1 IM a day for 30 days in a row. He claims beet juice is one of his "secrets". All along, I thought his secret was just being part mad man.
