Pumpkinman Triathlon

The Pumpkinman Triathlon is a Halloween-weekend multisport race on Saturday, October 31, 2026 at Boulder Beach in the Lake Mead National Recreation Area near Boulder City, Nevada. This festive BBSC event offers triathlon and aquabike formats plus relays, with a fun, costume-friendly Halloween spirit layered over a well-run course. Athletes swim in Lake Mead's clear water, ride on scenic park roads through the desert, and run along the lakeshore, all in comfortable late-October temperatures. It's a great choice for triathletes who want to close out the season with a lively, family-friendly atmosphere. Register online through the event page, and gather friends for a relay if you'd like to split the distance. Arrive early to rack your bike, set up transition, and enjoy the holiday-themed festivities.
