One of the four men who came up with the concept of the modern triathlon will be speaking Thursday night in Tahoe City.

Dan Hendrickson will be talking Sept. 19 at 6:30pm at the Gatekeeper’s Museum. A former Navy Seal, Hendrickson was one of four friends who originally came up with the idea of the triathlon. The concept was created with the intention of proving which athletes were more fit: swimmers or runners? The first triathlon was in San Diego in September 1974.

This Third Thursday Speaker Series event is free for North Lake Tahoe Historical Society members. A $10 donation is suggested for non-members.

Doors open at 6pm with a no-host bar.
