From the Organizer
We put the "ish" in "ten-ish". Just think of the extra distance as a FREE bonus.
This 12.4-mile course winds through the beautiful Red Hills Recreation Area in the Sierra Foothills. Winter is an amazing time to run in Red Hills. Water-crossings and mud add difficulty to already challenging, technical terrain.
NEW THIS YEAR!! - Giving you options is what DB is all about! This year we have added a second distance, giving you the choice between a 10ish mile or 10ish K event. Whichever distance you pick, you will still be seeing the Swisegoods at our only aid station.
