Course Maps & Details

Swim Course Details:

The Vineman AquaBike swim is staged at Johnson’s Beach in Guerneville, California. The swim takes place in the Russian River. 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 go to for full rules on wetsuits.)

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. (Please note that the Full AquaBike participants complete two loops of the swim course.)

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.

The dam at Johnson’s Beach is a seasonal dam which is up only in the summer months. The dam is scheduled to be in place by mid June and will remain in the river until the end of September.

Bike Course Details:

The 56 and 112 mile point-to-point bike portion of the Vineman AquaBike passes through the heart of Sonoma County’s wine country. Shortly after beginning the ride beneath the redwoods in Guerneville, it is off through miles and miles of vineyards! Dozens of wineries and literally hundreds of vineyards line the Vineman bike course.

The bike begins at Johnson’s Beach in Guerneville and finishes at Windsor High School. Aid stations are located approximately every 13 miles and have: bottled water with sport tops, single serve Gatorade Endurance with sport tops, mini Clif Bars and bananas.

The gently rolling hills are challenging, but not overwhelming. Although open to traffic the roads are lightly traveled and will be marshaled by USA Triathlon officials. 

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

Chalk Hill, the largest hill on the course is approximately 385 feet above sea level at its crest. The bike course begins at approximately 50 feet above sea level and ends at approximately 100 feet above sea level.
