I've been running ultramarathons for over a decade and now I'm turning 40. This show explores taking a big picture look at how to keep working on self improvement when the window for (personal) peak performance is closing and perhaps learn some things I wish I'd of known sooner. I'll explore diet options like keto and high fat low carb, training at lower intensities using methods like MAF, rest, recovery, strength, mobility, and race performance in my experiment of one.
