Beginning in October 2006, the first annual San Jose Rock N Roll Half Marathon will be held.

A popular walking and bicycling path is the Los Gatos Creek Trail. As of 2006, it begins in the Willow Glen neighborhood at Meridian Ave in San Jose. It extends twelve miles southwards through Campbell and into Los Gatos, connecting with trails in the open space preserves in the nearby coastal mountains.

The paved Stevens Creek recreation trail runs north along the creek just west of highway 85 beginning at El Camino Real in Mountain View. Overcrossings are a very convenient way to avoid all of the motor traffic, and it's deservedly popular, especially on weekends. After passing Moffet field and NASA Ames, it veers to the west along the bay shore, where a popular destination is the Mountain View shoreline park, with its pond, the historic Rengstorff house, a golf course. Off the end of San Antonio road in Palo Alto, the paved trail continues northwest along the frontage road; an unpaved alternate along the levees loops around to Bixbee park and the Palo Alto duck pond.

A newer trail path, the Guadalupe River Park and Gardens has been taking shape in recent years. At the northern end, it is unpaved (late 2008), but open as far as highway 237. A paved trail runs along San Tomas Aquino creek, east of Great America Parkway, between highway 237 and Monroe St in Santa Clara (south of Scott Blvd just finishing construction in late 2008). There is something of a hodgepodge of trails parallel to Highway 237 between Moffett park and Milpitas, but they jog around a bit and are not always signposted as well as they might be, so a certain amount of persistent exploration is needed to find good bike routes along here.

The San Jose area is also the site of some notable bicycling, including races about Mt Hamilton, the highest point in San Jose at over 4000 ft in altitude. Highway 35, Skyline Blvd, is great road bike country between highways 9 and 92, and there are many tens if not hundreds of miles of single-track and fire-road trails for mountain bikes.

There are several 25 yard length pools in San Jose proper. The nearest 50m Olympic length pools are found at the aforementioned International Swim Center, at the De Anza College (Cupertino), at the Fremont High School (Sunnyvale), West Valley College (Saratoga) and Stanford University (Palo Alto).
