This is the eighth year of Tour de Nash, a day of bike-riding activities across the city aimed at raising funds for Walk/Bike Nashville, which works to make Nashville a more pedestrian- and bike-friendly city. But in a way, it’s a new event this year, now that the Music City Bikeway — a 26-mile route connecting Percy Warner Park with Percy Priest Dam via downtown — is complete. That made it possible to create the 62-mile Metric Century, the longest of the three TDN rides scheduled. There are also the Gran Tour (28 miles) and the Family Ride (eight miles, and free). Youngsters who aren’t ready for the long haul just yet can spend the day learning bike safety and having fun at Camp Vandy while their parents pedal around town.
