Here is the MAN of high altitude running, Matt has the highest Vo2 max ever recorded by a runner (above 90), higher than Lance Armstrong. I watched Matt float by me at Pikes Peak and the Fila races in Aspen Colorado years ago. I also lined up with Matt at the Leadville 100 as he took off to return over Hope Pass miles in front of the field. Amazing..
I ‘d like to see Him and Kyle duke it out at Hardrock..
