The Top 5 Running Show is back. This week, we take a look at a more intimate and autumnal Boston Marathon, Chris Thompson's UK Olympic Trials triumph, high schooler Hobbs Kessler's mind-bending two miler, and ASICS' attempt at creating two new "Vaporfly Killers"

Each week, two of our contributors or special guests face off in The XC's Top 5 Running Show, dissecting five stories from the week in the world of distance running and track and field. They offer their best and hottest takes in order to score points.
