If you have resolved to hike more in 2018, check out East Bay Regional Park District's 25th annual Trails Challenge. It runs now through Dec. 1 for participants to earn a free commemorative pin for completing a minimum of 26.2 miles of trails or by hiking five trails.
Trails Challenge 2018 is a free, self-guided program presented by a partnership between East Bay Parks, Kaiser Permanente, and the Regional Parks Foundation. Free printed guidebooks and T-shirts are available at participating visitor centers or the district's administration office in Oakland. The Sunol-Ohlone Regional Wilderness, 1895 Geary Road in Sunol, is one of the participating visitor centers.
No registration is needed to participate. Just go to www.ebparks.org/TrailsChallenge to download the guidebook and get started. The program is run on the honor system with no verification of the hikes required.
The guidebook includes detailed trail descriptions for hikes in 20 regional parks or trails, ranging from easy to challenging. There are trails open to hikers, bicyclists, dogs and equestrians, and many are wheelchair accessible. To complete the challenge, hike five of the trails -- or 26.2 miles of trails.
The East Bay Parks also offers naturalist-led hikes throughout the year, including at Del Valle and Sunol. The calendar of events is on the website.
The park system has 121,030 acres in 73 parks in Alameda and Contra Costa counties, including 1,250 miles of trails.
