Pre-covid, Pete would lead these incredibly hard hill rides out of Bike Kinetic every Tuesday morning starting at 6 a.m., even in subzero temps in winter, in darkness, in bitter cold, in summer rain. This ride is the culmination of all of them. I think there is something like 300 turns in the steepest, gnarliest sections of Arlington and Falls Church.
