The Complete San Jose Running Guide 2025

Local guide to running in San Jose: best routes, races, clubs, tracks, weather tips, and race-day logistics from Los Gatos Creek to Alum Rock.

If you’re running in San Jose, you get the best of California miles without the crowds. This San Jose running guide covers where to run, which races to target, how to train by workout type, and exactly how to handle race-day logistics. I’ll share the insider details locals use to keep training smooth through busy tech weeks, warm afternoons, and those rare but mighty winter rains.

Why run in San Jose

San Jose sits in the Santa Clara Valley, framed by the Santa Cruz Mountains and Diablo Range, so you can pick flat paved paths for marathon training or roll into real hills for strength. Mornings are usually cool. Trails dry fast after rain. And the route network connects neighborhoods in a way that makes point-to-point long runs easy to plan with light rail or a rideshare back.

Primary reasons people love running here include the linked trail system, an active but welcoming club scene, and a race calendar that ramps from early spring into late fall. If you are visiting for work, you can land at SJC and be on a paved trail within 10 minutes. If you are new to the area, you can build a full season without leaving the South Bay.

The best running routes in San Jose

Los Gatos Creek Trail

If you ask a local where to start, they will say Los Gatos Creek. The paved multiuse trail runs roughly 10 miles from downtown San Jose through Campbell to Los Gatos, then it climbs on gravel toward Lexington Reservoir. Park at Campbell Park for an easy out and back, or start at Los Gatos Town Plaza if you want coffee at the finish. Restrooms and water sit next to the Campbell Park lot and again at Vasona Lake County Park. After big winter storms the underpasses near Camden can flood, so check county park alerts before you head out. For workouts, use the flat middle section between Campbell and Vasona for tempo and marathon pace. If you want a hill kick, continue south past the dam and climb the gravel service road toward Lexington.

Guadalupe River Trail

This is the downtown backbone. It runs along the river from Alviso near the Bay to the SAP Center and the airport, with spurs toward the convention center. Use it for prework shakeouts if you are staying in a hotel near Almaden Boulevard. It is flat, exposed to wind in the northern reaches, and usually quiet in the early morning. Lighting varies and some sections feel isolated after dark, so run daylight or with a buddy. Good access points include Arena Green near the SAP Center and the trail lot at Trimble Road. There are water fountains near Arena Green and at some pocket parks along the way.

Alum Rock Park

Alum Rock is the local trail runner’s first love. The North Rim and South Rim trails form a loop above Penitencia Creek with honest climbs and shaded switchbacks. You get views of the valley, quick creek crossings after rains, and redwood groves tucked into the canyons. Start from the Penitencia Creek Road entrance. Bathrooms and water are by the visitor center. The loop ranges from 6 to 8 miles depending on your connectors. Expect warm temps by late morning in summer and watch for bike traffic on weekends.

Coyote Creek Trail and Hellyer County Park

For long, flat marathon training miles, Coyote Creek is money. Start at Hellyer Park and head south. The path rolls gently through open space for as long as your plan needs, with mile markers placed at regular intervals. Bring a bottle because fountains can be spaced out between trailheads. The Hellyer lot has restrooms. This is also a go to for Sunday long runs because it stays runnable after rain.

Alviso Marina and the Bay Trail

When you need wind practice and big sky, loop the levees at Alviso Marina County Park. The flat dirt and gravel perimeter paths give you 5 to 9 miles depending on turns. Parking is free and the gates close at sunset, so start early. You will feel the breeze coming off the Bay and you will get salt on your shoes. It is great marathon pace practice when you want to build resilience in real conditions.

Santa Teresa County Park and Quicksilver

Both parks sit in the foothills south of the city and both serve trail workouts with views. Santa Teresa’s Mine Trail to Coyote Peak is a short, steep grinder that is perfect for hill repeats. Almaden Quicksilver County Park links Mine Hill, Randol, and Capehorn for larger loops. The Mockingbird Hill entrance has bathrooms and a posted map. The footing is mostly fire road with some rocky sections. Rattlesnakes are a reality in warm months, so watch your step and give them space.

Communications Hill Stairs

For strength without a mountain, locals run the staircase at Communications Hill off Quimby Road and Capitol Expressway. The main staircase has long flights with landings that let you settle rhythm. It gets busy after work. Go early or accept the shared flow and treat it like a social hill session.

San Jose race calendar highlights

San Jose does not have a massive standalone marathon today, but it hosts a deep slate of half marathons, fast 5 and 10ks, and classic local events. Always confirm dates in RaceThere since weekends shift year to year and permit calendars change.

• Rock ‘n’ Roll San Jose Half Marathon and 10k usually lands in early October with a downtown start. The half is flat and spectator friendly. Stay near the convention center or the hotels along Almaden Boulevard to walk to the corrals.
• Silicon Valley Turkey Trot anchors Thanksgiving morning. It brings thousands downtown for 5k and 10k races. Roads close early and parking fills, so plan to arrive by light rail or get dropped off near the SAP Center.
• The 408K Race to the Row is a South Bay tradition that typically runs late winter. It starts near the SAP Center, finishes at Santana Row, and features the Mariachi Mile that keeps your cadence honest.
• Santa Run Silicon Valley brings a fun December 5k to downtown with costumes and family waves.
• Almaden Quicksilver 50k and 100k, held in spring, serves the trail and ultra crowd on the slopes above the valley. Expect stout climbs, a well marked course, and a community feel.

Search these and more on RaceThere, then filter by distance, surface, elevation, and even swag if that is your motivator. Save your short list and build a season that steps from 5k up to the half, or anchor with a fall half and tune with spring 10ks.

Where to train by workout type

Speedwork and tracks

Los Gatos High School’s track is commonly used by the community outside school hours when it is not reserved. Respect signage and closures. Westmont High and other public high school tracks in the Campbell Union and San Jose Unified districts are sometimes open after hours, but access varies by campus and day. If a track is closed, move the workout to the flat stretch of Los Gatos Creek between Campbell Park and Vasona, or use 1 km repeats on the paved Guadalupe River Trail downtown. Bring your own water. Spigots at tracks are not guaranteed.

Hills and strength

Use Communications Hill stairs for short, punchy reps. For sustained grades, climb the Mine Trail at Santa Teresa or take the Mine Hill to Randol loop in Quicksilver for longer threshold efforts. If you stay on pavement, Hicks Road from Camden to the base of Mt. Umunhum gives you a controlled 3 to 4 percent grade. Go early because traffic increases mid morning.

Long runs

Coyote Creek south from Hellyer gives you uninterrupted flats that make fueling practice simple. Los Gatos Creek lets you start steady and finish with the Lexington climb for a late effort. If you want a trail long run, link Quicksilver to Calero County Park via Rancho San Vicente for a rolling 15 to 20 miles on wide fire roads.

Recovery and easy days

Take the Lakeside Loop around Vasona Lake and the Los Gatos town paths. Mix in the Bay Trail at Alviso when you want soft surface and sea air. Keep the heart rate low and stop for coffee at Los Gatos Coffee Roasting Company or at Chromatic Coffee near The Alameda.

Running clubs and group runs

The South Bay is collaborative. You can show up and find a friend at most group runs. A few staples to know:

• Quicksilver Running Club of San Jose supports trail and ultra runners with weekend group runs in Almaden Quicksilver, Henry Coe, and beyond. Expect a friendly crowd that knows the park maps by memory.
• San Jose Fit offers structured marathon and half marathon training cycles that meet on weekend mornings, often from Campbell Park. It is a good choice if you like coached long runs and plans that ladder up.
• Fleet Feet San Jose and Fleet Feet Los Gatos host weekly fun runs and seasonal programs. Schedules shift with the race calendar, so check their store pages for current days and start times.
• Running Revolution in Campbell regularly posts shop runs and speed sessions. Staff are plugged into the local scene and are quick to point you to the right group for your pace.

If you prefer to keep it solo but want company nearby, start from Campbell Park on a Saturday at 8 a.m. You will see every pace from sixes to elevens on the Creek Trail.

Public tracks, parks, and access

Parks in Santa Clara County post open hours at trailheads. Most close at sunset. County parks like Vasona, Hellyer, Almaden Quicksilver, and Santa Teresa have bathrooms at main entrances that open around sunrise. City parks such as Campbell Park and Los Gatos Town Plaza have restrooms that follow city schedules and may open later on weekdays. Bring a backup plan for water during early sessions.

Track access changes by season and school policy. The general rule is simple. If gates are open and there is no posted restriction or scheduled use, the community can jog respectful laps. If teams are present, yield completely. Avoid metal spikes. Do not bring dogs onto tracks. When in doubt, do your repeats on the trail.

Weather, air quality, and seasonal tips

Weather shapes running in San Jose less than in most cities, but a few patterns matter. From November to March you will see rain systems that fill creek underpasses and close dirt singletrack for a day or two. Trails like Quicksilver handle moisture well, but steep connectors get slick. In late spring and summer the afternoons warm quickly. Aim for early starts and shaded routes like Alum Rock or Los Gatos town paths. The Bay levees at Alviso stay breezy and cooler.

Air quality can dip in late summer and early fall during regional wildfire events. Check AQI before workouts. If the AQI rises above 100, move indoors or keep it easy. Pollen runs high in spring. If allergies get you, consider the Bay Trail where wind helps.

Hydration sneaks up on runners here because mornings feel cool, then temperature jumps. A small flask is enough for most 60 minute runs. For long sessions, especially on trails, carry a vest. Water is available at major parks but can be off for maintenance without notice.

Safety and etiquette

The trail network is shared with cyclists and families. Keep right, call your pass, and roll headphones down to a low level. In summer rattlesnakes are part of the ecosystem on dirt routes, especially at Santa Teresa and Quicksilver. Give them space and they will go their way. In downtown sections of the Guadalupe River Trail, run with a friend at dawn and dusk. Lighting varies and some underpasses feel isolated.

Most park lots are safe during daylight, but do not leave valuables in view. Campbell Park fills early on weekends because of youth sports, so arrive with buffer time or park on nearby side streets where posted.

Getting around for training and race day

Public transit helps with point to point runs and race mornings. VTA Light Rail serves downtown, Japantown, Diridon Station, and corridors south to Capitol and north toward the airport. Trains allow bikes and make it easy to meet a friend and finish together. Diridon Station brings Caltrain from the Peninsula and Amtrak’s Capitol Corridor from the East Bay and Sacramento.

For Rock ‘n’ Roll and the Turkey Trot, book a downtown hotel and walk. The Marriott, Westin, and other convention center hotels sit within a few blocks of typical start lines. If you drive, garages near the SAP Center often offer race morning flat rates, but they fill before 6 a.m. Check the event guide in RaceThere the week of the race for current closures and best access points.

Running stores, coffee, and recovery

You can get dialed in quickly with the right stop.

• Running Revolution in Campbell is a local favorite for shoe fittings, trail shoe options, and honest advice. They know how the Creek Trail rides underfoot and which lugs you need at Quicksilver.
• Fleet Feet San Jose and Fleet Feet Los Gatos cover road and trail, host training groups, and keep an updated community calendar.
• Coffee near routes is easy. In Los Gatos, hit Los Gatos Coffee Roasting Company or Great Bear. Near Campbell Park, Blue Bottle at Pruneyard opens early. Downtown, Academic Coffee sits a short jog from the Guadalupe.
• Recovery options range from the YMCA pools for a shakeout swim to independent PT clinics along Bascom and in Los Gatos. Book ahead if you want a post long run sports massage on a weekend.

Sample week for a visiting runner

Monday easy 4 to 6 miles on the Guadalupe River Trail from Arena Green, with a few strides near the SAP Center. Tuesday track style intervals on Los Gatos Creek’s flat stretch from Campbell Park toward Vasona. Wednesday rest or 30 minutes easy around Vasona with a coffee stop. Thursday hill reps on the Communications Hill stairs at sunrise. Friday shakeout 3 to 5 miles at Alviso to stretch the legs. Saturday long run from Hellyer south on Coyote Creek with marathon pace miles. Sunday trail play in Alum Rock, short and scenic.

Planning your season with RaceThere

Use RaceThere to map your South Bay season. Search by city to pull up San Jose races, then filter by distance and surface. Pin the 408K for winter, a spring 10k, a summer trail race in Quicksilver, and a fall half like Rock ‘n’ Roll. You can sort by elevation gain if you want a course that suits your strengths. Each event page includes the essentials like parking, packet pickup, and start time so you spend less time hunting and more time running.

If you are new to the area, combine this guide with our marathon training and race day preparation resources, then build a plan that fits your work and family schedule. If you are visiting for a single weekend, use the routes above and grab a last minute 5k or 10k from the RaceThere calendar.
