Finisher swag reveal!
Every Stone Mill finisher this year will take home a custom Gear Bag Lite from SILO, made just for this race. It’s a great lightweight bag, and at 19" × 18" it’s big enough for your post-run clothes. It also doubles as a drop bag at your next race!

Still time to register for our big 50 Miler -- Stone Mill 50 Mile Race is in a month on November 7th. Help fill out the map -- $89 for 50 miles is the greatest race bargain out there! http://stone-mill-50-mile.org

Where is everyone coming from? There are 204 runners registered from 15 states, D.C., and two countries!

Maryland is leading the way with 107 locals, followed by 49 from Virginia and 13 from Pennsylvania. And we're going international: one runner is making the trip all the way from Alberta, Canada!

Our furthest entrant from within the U.S. is coming in from California, which is roughly 2,500 miles of travel to run 50 miles on the Seneca Greenway and Muddy Branch trails.

Don't see your state on the map yet? There's still time to change that.
