Longest Causeway Run & Wellness Walk

A run and walk across the Queen Isabella Causeway between Port Isabel and South Padre Island, one of the Valley's best-attended athletic events.

The Longest Causeway Run and Wellness Walk crosses the Queen Isabella Causeway between Port Isabel and South Padre Island — a bridge that is normally the only way onto the island by car, closed to traffic and given over to people on foot.

That is the whole appeal. You are walking or running across open water on a structure you have only ever driven, in January, with the Laguna Madre on both sides.

If you have never been

It is a January event and it is one of the best-attended athletic events in the Valley, drawing both Valley residents and Winter Texans, with the walk making it accessible to people who are not runners.

The logistics are the part to plan: the causeway is the only road onto the island, so closing it shapes everyone's morning.

Months, not dates. Annual events move and organizers announce their own — we will never guess one for you.

Dates change each year. We list the season rather than a date we cannot yet confirm. When Qué Hay opens, the confirmed dates, times and full programme will be here — and we will never publish a date we are guessing at.
