I had a great time and shaved over 10 minutes of my PB! Thanks 3M Half Marathon!!

There really is a “runners high!” And today’s 3M Half Marathon has me smiling from ear to ear! Austin is such a great running city!

Had an incredible morning thanks to 3m half marathon and smashed my previous PR by over 12mins! Not mad at it 😀 #runnerbliss

Big thanks to all the volunteers. And all the ATX folks out there to cheer us on. Always a 1st class event and so much fun!
