First distance relay race in my life, therefore no doubt there was the novelty of it. I was pretty satisfied with the experience and concept. As the first runner, the route was still rather warm, though in no way do I expect the organisers to do anything about that.
I do have a few suggestions for improvement
1) Race route - some pretty tight turns, though no issues with bottlenecks or hazards for me. I do agree with medic's point regarding the poorly lit loop under the stadium.
2) Hydration - I always wish for hydration to be provided in paper cups as they are easier to pinch and drink from, opposed to firm plastic cups.
I do have a question - do the second to fourth runners run under the stadium once per loop? As a first runner, I only ran under the stadium once, during the beginning of my second loop.
