Well, we respectfully ask you to think again
The cost of electronic timing for a half day race such as a marathon costs $2,000 to $15,000.
The cost of medical service for a half day race such as a marathon costs $2,000 to $20,000
Double that for a full day then multiply by 6 days and the costs add up. Very, very substantially.
Add to that the cost of the world class Race HQ and the National Park and the costs climb even higher. Just the lighting alone costs $275/day.
And then there are the costs of liability insurance and compliance costs. These days, it's necessary to prepare Event Management Plans, Emergency Management Plans, Medical Plans, Trail Impact Mitigation, Traffic Management Plans and so on.
