This is a monthly social run in the late Spring to early Fall at the Sudwerks Dock Store.  The "standing" meeting time is the first Friday of each month at 6 pm, and the distance is typically 1 mile to 5k (out-and-back) on the bike paths in Davis.  Afterwards people tend to hang out on the patio area to eat, drink, and socialize.  Sometimes there's live music or a food truck arranged by Sudwerks.
