Thank you for joining us!

It was a great day at the 2019 Mason Run @ Chester Woods.  The 50K kicked us off shortly after the lightning subsided, we dodged some storms and it made the day a bit cooler, in fact, incredibly nice for running!  The 5K and 10 Milers got on the trail about 2 hours later... lots of smiles, and lots of miles!  Many thanks to all the participants, and all the volunteers!  You are the best of the best! 

*Our Promise for Next Year: More Pickle Juice.  More Craft Beer.


Race swag includes a Mason Run tee shirt and a Mason Run Mason Jar at the finish line to fill with your beverage of choice!
