Course Maps & Details

Swim Course Details:

The Full Vineman 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 the rules regarding wetsuits.)

The swim is a two loop course with an in water start that begins in front of the dam at Johnson’s Beach and proceeds upstream to the turn around point where the swimmers will then return to the start point and begin their second loop. Swimmers will keep the swim buoys on their left for the entire swim. A neutral area, which is marked with buoys, 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.

The Russian River is dammed in a number of locations near Guerneville and it almost never rains in Sonoma County from early June to mid October, so there is very little current in the river. 

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.
