If you bandit to have the experience of a race, you are a leech.
If you want a race experience, pay for the experience or set up your own weekly fun run/time trial.
You make an exchange to experience the race - you pay and you get that race experience. If you have a moral objection to paying, do it at some other time with people you recruit yourself. You didn't set up the logistics, so you get to pay for the benefit of having the other runners, intersection patrols, clear running area. It is a social contract.
