Dads, it's time to take on the ultimate training day with a guaranteed hall pass to slay the world-class singletrack in Annadel State Park in Sonoma. While we're at it, let's have someone else drive you up there in a big bus stocked with food for the way up and adult beverages for the way home. Added bonus: meet other Glorietta mountain-biking dads for future rides and do it all guilt-free, because it's... for the kids!
