The 100 Miles for Moss virtual challenge is back for the SEVENTH year!

Challenge yourself to complete 100 miles on horseback, on foot, on a bike, on a carriage, or a combination of any or all of the above between September 1, 2026 and December 31, 2026 and show your support for The Walthour-Moss Foundation.  Participants will log their mileage using runsignup.com and receive the 2026 100 Miles for Moss commemorative medal upon completion of their personal challenge.  For some it may take a week for others it may take months.  The challenge is up to you.   Mileage updates will be posted and we encourage participants to post pictures of their progress (and with their finisher medals too!) on our event page. Make your challenge your own and tell us and your fellow participants about it.   Mileage may be completed anywhere. And we do mean anywhere.  In WMF? Yes for all but the cyclists.   While hacking around the neighborhood? Sounds great! In a Dressage ring? Yes! On your morning run? Yup!  While shopping? Sure! In another country? Absolutely (though we are unable to mail medals outside of the US). 

Sign up for the 100 Miles for Moss challenge, make a your challenge your own, and show your support for the land that we all enjoy and use.
