An 85 year old man did a sub 4 hour marathon. I rant about how most of what we think of as age related decline is actually due to lack of physical activity.  I also break down what's In vs Out in 2017 in mountainbiking, and break down a GMBN video pitting an enduro bike against a cross country bike in a race.  Enjoy!
