Frontier 300 by Scott

From Colvend, this is an "extraordinary challenge" built around gravel, forests, and sustained open-country effort rather than quick road-race pacing. Frontier 300 by Scott feels like a self-powered crossing: out past Castle Douglas country, New Abbey Corn Mill, Galloway Forest Park, and Caerlaverock Castle, with "spectacular landscapes" providing much of the scenery. Expect a rugged, outdoorsy day or two on gravel, with significant climbing, 10 forests to navigate, and a border crossing that serves as a memorable marker when your legs are tired. The participants are cyclists, adventure enthusiasts, and families on the periphery, and the best quirk is the conclusion: a "warm beach party" with a genuinely "convivial atmosphere" instead of a standard finish chute.
