Open water swimming

The 2017 open water swim season at Grant Ranch has come to an end. Check back in early 2018 for next season updates! Thank you for swimming with SwimLabs!

2017 Grant Ranch

Grant Ranch will offer swimmers an opportunity to train for their upcoming events or to simply practice their open water skills. There will be two courses available, 1/2 mile triangle or a 1.2 mile loop.  Grant Ranch is free of motorized boats, which allows for a very safe environment. The course is full of large orange sighting buoys to make sighting simple. There will be plenty of volunteers on hand to assist with wetsuit zippers, help with open water technique questions or simply provide a word of encouragement. When you are all done with your swim, Grant Ranch has hot showers and a locker room to allow you to get prepared for the rest of your day.
