The Organizing Committee (OC) of the Halong Bay Heritage Marathon 2025 hereby announces the official Start Times and Cut-Off Times (COT) for the 42km and 21km race distances. These time regulations ensure the safety, fairness, and international-standard operations of Vietnam’s first and only World Athletics Label Road Race, hosted on one of the Top 50 Most Beautiful Running Routes in the World (Runner’s World UK).

Important Notes for All Athletes

To ensure a smooth and timely start for all participants, athletes are required to pay close attention to the following guidelines:

1. Arrival Time Responsibility

The Organizing Committee will not be responsible for late arrivals caused by:

  • Baggage drop-off delays

  • Parking congestion

  • Late arrival to the venue

Athletes must manage their schedule and arrive early.

2. Recommended Transportation

To avoid traffic congestion near the event venue, we strongly recommend using:

  • Public transportation

  • Ride-hailing services booked in advance

This helps ensure timely arrival and reduces traffic pressure in the racing area.

3. Benefits of Arriving on Time

Being at the venue early ensures that athletes can:

  • Warm up adequately before the race

  • Enter the correct starting pen according to race regulations

  • Avoid being denied access to the start due to late arrival

We wish all athletes the best preparation as you get ready to conquer the Halong Bay Heritage Marathon 2025. We look forward to welcoming you at the starting line—on time, full of energy, and ready to break through on the heritage course!
