Bob Hearn - super smart ultra-runner and recent winner by more than a day of The Heart of The South 350 mile race, joins me for a great chat about ultra-ultra distance races.  (Is that a term?)   Until last lear, I thought Cocodona was the longest race, but I was just learning.  There's a whole other spectrum of longer distances, from 6 days on a track to journey type point to point runs.  "A vacation without a car".  Bob has a PHD in Computer Science from MIT, so he's pretty smart, and he has won numerous ultras around the world, so he is pretty fast and durable as well.  He discusses his story from his first 10k to his recent win at HOTS.  I think you will enjoy his perspective and help me celebrate because episode 45 marks the 1 year anniversary of Miles With Marty!!  Thank you so much for your support.  I hope you like the little change in format!  LMK.Here's a link to Bob's blog:The Puzzle of Running (bobhearn.blogspot.com)
