Trenton-Princeton, NJ

Running around Trenton-Princeton stays mostly flat along the Delaware River and local park systems, with the Great Peace Valley 5 Miler offering a classic local race option. Cyclists have serious terrain within 15km: the Sourland Mountain region rolls hard with sustained climbs to 150m, drawing riders to the Sourland Spectacular 2026 and longer gravel routes, while flatter group rides head south into South Brunswick on the Tour de South Brunswick course. The region bridges urban flatland with Piedmont hill country, making it a split personality for endurance sports—runners stick to river paths, cyclists split between flat commute routes and genuine climbing just inland.
