Adding a solo division to the 15.5 kilometer course at 6,000 feet (1829 meters) of altitude in water temperature between 12-15°C (55-60°F) puts the event on par with some of the toughest marathon swims around the world.
The solo division is held concurrently with the relay portion of the event.
“Many Olympians, world champions, and professional marathon swimmers have participated in the Trans Tahoe Relays. But now soloists can race and compete on this famed course – and enjoy the unparalleled ambience of the pre- and post-race activities in Lake Tahoe. Lake Tahoe is also famous for solo crossings but now the venue is part of the new Ultramarathon Swim Series that ties marathon swimming events around the world in a unified manner.”
