Is there a way to keep your speed when you are near the red light? I've seen people still running in the red light but when i try it my character gets very slow. What's the trick?

I don't know of any trick or strategy that allows you to run at normal speed near the red light, where did you see this trick beign performed as i don't know how it is done either.

I don't know for sure, but during one of my runs, I managed to run in the red light by going backwards into the area ... but it only happened once I don't know if that was the exact reason.

have you tried it multiple times?

I tried it three times, but I didn’t succeed in any of those attempts

maybe there is a specific path you need to take
