Ohlone 50K Trail Run
17 May 2020
The Ohlone Wilderness 50K is recognized as one of toughest 50 Kilometer trail races in the United States. This classic and iconic ultramarathon is held along the entirety of the Ohlone Wilderness trail, in the eastern region hills of the San Francisco Bay Area. Traveling across the land once home to indigenous tribes, and now habitat to abundant wildlife, the course traverses four regional parks: Mission Peak Regional Preserve, Sunol Regional Wilderness, Ohlone Regional Wilderness, and Del Valle Regional Park. With near 8,000 feet climbing, and high ridges including 2,517 ft Mission Peak and leading up to the 3,817 ft summit of Rose Peak, you will put your grit and endurance to test, all while treated with spectacular views of the Bay Area and surrounding mountains.
The distance is 31 miles, with 7,800 feet elevation gain, and 7,440 feet descent. A mix of trail and fire roads, a large section of the terrain is extreme, exposed and rugged. The vast majority of the course follows the Ohlone Wilderness trail. The course deviates from the marked Ohlone trail in several places in order to add distance or to access water.
Plan for heat. It’s hard to bet against hot weather. Of course, we’ve had rain, hail, and forty-degree temperatures. In most years, race day has started with fog in the morning that gives way to increasing heat and sun throughout the day Temperatures are usually in the 80’s to mid-90’s but have topped 100 in some years. Be prepared! Best advice is to watch the forecasts and prepare accordingly. Wear a hat, bring your sunglasses, slather on the sunscreen. By all means - carry water. It's recommended carrying at least two bottles.
