3 marathons and a lifelong runner, I have become super particular about what I need to succeed. I love the Nike bra because it is the only one that gives me full support. The gu is for you long runners that need some extra energy on mile 10. But my favorite product whether it’s a 3 mile run or a 26 mile run is the feetures socks. Never would I think that a sock would be so important but these are an ABSOLUTE MUST! Treat your feet kindly run LTKfit LTKRefresh LTKunder100
