Official date status
Hoover Dam Marathon is listed for December 5, 2026. This date refers to the race represented in this guide; other distances and expo activities may run on different days.
Official date information checked on 2026-10-18. This check covers the date status, not entry availability or final race operations.
Hoover Dam’s tunnels and two loops do not cross the dam
The marathon repeats the half-marathon circuit, so the return toward Boulder Beach after the first loop is not your finish. Follow the current full-distance turn instructions and keep track of which loop you are completing. Runners in shorter categories may leave the shared route earlier.
The switchbacks are part of an undulating course rather than a continuous flat rail trail. Prepare for the uphill return from the dam viewpoint as well as the descent. Practise on comparable packed-dirt and paved surfaces and choose footwear you know, taking the actual weather into account.
The organizer explicitly says the course does not go over Hoover Dam. Give supporters the permitted race viewing points instead of arranging a meeting on the dam itself. Check the final tunnel and trail instructions, stay alert to other runners and follow marshals where the route changes surface or direction.
Packet pickup is listed from 07:00–08:30, but marathon runners start at 08:00 after a 07:55 briefing. Arrive early enough to complete collection and preparation before those times. The 14:05 closure is six hours and five minutes after the scheduled marathon start; verify any additional gates and include stops in your plan. Save the Boulder Beach picnic-area directions and confirm park access and parking requirements. BBSC also stages a separate Lake Mead race in January, so check the event name and date on your confirmation rather than assuming the two programmes are interchangeable. Use the final aid chart to choose familiar supplies and carrying capacity. No 2027 Hoover Dam edition is confirmed in the reviewed information, and the December 2026 date should not be moved forward automatically.
