Due to the impacts of COVID-19 on planning major events and large gatherings, the City of San Luis Obispo today announced the cancellation of the 41st annual SLO Triathlon which was scheduled to take place on July 26, 2020.

For 40 consecutive years, the City has hosted the SLO Triathlon on the fourth Sunday in July.  Putting on the half-mile swim, 14-mile bike and over three-mile run requires months of planning and preparation. During the COVID-19 emergency, the City’s primary focus is on providing essential services to protect the health and safety of the community. Given these factors and the importance of ensuring a safe event for participants, community, volunteers, staff, and sponsors the City has decided to cancel the event for this year.

“We want to thank our community for their continued support and recognition of the importance of slowing the spread of COVID-19 in our community.  Similar to other large sporting events, we are canceling the SLO Triathlon until next year.  We are looking forward to coming together as a community for the event in 2021,” said Parks and Recreation Director Greg Avakian.
