Course Maps & Details

Swim Course Details:

The Ironman 70.3 Vineman swim is staged at Johnson’s Beach in Guerneville, California. Water temperatures are typically between 72 and 76 degrees. If this is the case on race morning wetsuits will be allowed as this falls within USA Triathlon guidelines. (please refer to the USAT website for details of the rules) 

The swim course is an out and back course which starts in front of the dam at Johnson’s Beach and proceeds upstream stream to the turn-around point. Swimmers will keep the swim buoys on their left-hand side for the entire swim. A neutral area, which is marked with buoys, where there are no swimmers will separate the swimmers on the outbound and return legs of the swim. The swim course, which averages between 4 and 7 feet in depth, will be monitored by lifeguards in kayaks. 

Between the Russian River being dammed in a number of locations near Guerneville and the fact that it almost never rains in Sonoma County between June 1st and October 15th, there is very little current in the river during this time period. Under typical conditions, a 25-minute mile swimmer should expect it to take about one minute longer to make it to the turn-around point (swimming against the stream) than it would to return back to the swim finish from the turn-around (swimming with the current.)

The dam at Johnson’s Beach is a seasonal dam which is up only in the summer months. The dam is placed around mid-June and will remain in place until the end of September.

Johnson’s Beach has been a favorite summertime spot in Sonoma County for decades. The beauty of the redwoods which line the banks of the Russian River, the serenity of the flowing river, and the down-to-earth people who run Johnson’s Beach and Resort make it a truly special place. The concession stand at Johnson’s Beach is open daily and is famous for its giant draft beers and its fresh grilled hamburgers.

Oomph! Bike Course Details:

The Oomph! bikke course for the Ironman 70.3 Vineman is simply a great course. It is challenging, but not too difficult. Its many rolling hills and curves are technically demanding. It has just under 2000 feet of climbing, including a 385 foot climb on Chalk Hill, which is enough of a challenge because of the location. Its comes at mile 45 of the ride...keeping you honest in your training and race pacing. But most of all the course is extremely beautiful, passing endless miles of vineyards and dozens of wineries.

The bike begins at Johnson’s Beach in Guerneville and finishes at Windsor High School (approximately 17 miles away from its starting point). Aid stations are located at mile 18, 29, and 40 and will be serving water(in single use,sport top bottles), Gatorade G Series Pro 02 Perform, and PowerBars.  NOTE: Gatorade G Series Pro 02 Perform contains an tailored to help replace the the fluids and electrolytes elite and endurance athletes lose during their longer, more intense workouts, with twice the sodium and higher levels of potassium and magnesium to support longer, more intense occasions.

Although open to traffic, the roads are lightly traveled but will be intensely marshaled by USAT officials.

Air temperatures generally range from the low to mid 50's early in the morning to daytime highs between 80 and 95 degrees.
