We often tend to think of things in purely practical terms with all things having been considered and taken into account, but at the end of the day if you truly want to understand how the world works you need to look into philosophical approaches to these sorts of things as well. For example, when you think of a relay race you might assume that it is something that kids do every so often and that it might have the potential to provide you with some exercise but that is where the benefits of this sort of thing tend to stop.
However, if you look at it a bit more philosophically you would notice that relay races provide a much deeper benefit than you have initially realized. Taking part in overnight relay races means that you would have to rely on others to complete the task that you have started. What this means is that by taking part in these kinds of races we can start to develop a more community oriented approach rather than assuming that everything we do is for ourselves and that we are the only ones that can end up getting things done all in all.
It is important to remember that we are not just individuals who are responsible or ourselves. Rather, we are part of a wider society, a community of people all of whom need to work together in order to better our lives. Relay races help us understand these kinds of things, and by making them happen a lot more often we can help the world become a much more peaceful and reasonable place to live in even if we have other problems that also need to be addressed.
