"At the Shamrock Shuffle I ran a 37:33. That is the best time I have ever had for a race and because of Chicago Endurance Sports I was able to do this. I've never run under 8:00 min miles for a race in my life and can only attribute it to your guidance. You guys/gals are the BEST! THANK YOU, THANK YOU, THANK YOU!!!
