Half Marathon races near Modesto

Modesto Base Miles And Fast Flats

Modesto hosts 3 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Modesto runners get a lot done without making it complicated. Locals use Dry Creek Trail, Graceada Park, Roosevelt Park, and the Graceada Park neighborhood for easy miles, intervals, and shakeouts. The main routes cover 61 km with 31 m of gain, so the legs stay honest without turning the day into hill work. Modesto Moves keeps the social side moving, and Teens Run Modesto brings 221 students with 55 mentors into the routine. Modesto Marathon is the anchor event, with Blazin' Eagles 5K Fun Run/Walk, CASA of Stanislaus County 5K, and The Big Run Modesto filling the calendar.

Modesto riders live on flat speed, steady Z2, and canal-side base miles. The city gives riders Class I, II, III, and IV bikeways, so a weekday spin can stay simple. Sunday Smasher leaves Mistlin Park at 8am and gives locals 40 or 56 miles to work with. Wednesday Night Ride leaves Funsport Bikes at 6pm and covers 18 miles total. The typical local route runs 35 km with 343 m of climbing. The bigger climb days point toward the Coastal Ranges or the Sierra Nevada. Bike N' Trike 2026 sits on the local race radar.

Modesto seasons reward riders and runners who respect the heat. Locals stack quality work through cool to mild winter days, then shift summer training early because the city gets hot, dry afternoons. January gives runners and cyclists a 38°F to 53°F range, so long runs, tempo work, and steady road rides can feel clean when the rain stays away. Summer turns Z2 into a dawn job, and intervals need shade, bottles, and a short leash. Winter brings moderate rainfall, greener miles, and some chilly dry mornings. Locals still keep moving, just with more layers and a little more patience.
