The Cliff Backyard Ultra

August 18, 2019

Wellington Lake, Bailey


The Cliff Backyard Ultra is a unique individually supported stage-style marathon swimming competition.  This swim offers a challenging swimming opportunity for long-distance swimmers.  In this event, swimmers have the chance to test their swimming strength by completing a 1.5 Mile loop each hour, on the hour, until they no longer desire to continue.  The last swimmer to complete a lap earns the title of “Last to Fail.”

Racing will begin Saturday, August 17, at precisely 6:59 am. Swimmers will complete a 1.5 mile loop on triangle race course, every hour. Racing will continue every hour until no swimmer completes a loop. There will be one award for the Last To Fail. To be the “Last to Fail” you must complete one more loop than the second-to-last to fail.

For 2019, we have a cap at 30 participants.
