Well first off, the first days are the worst. If you could avoid being in the deep woods on those days, you would be better off. Hunters are supposed to identify their target carefully. In practice they may be looking for only a few salient features, like movement. The fact a person is wearing bright colour (good thing) does not mean that is the filter a hunter is using. There is a lot of brown in the woods, so the most likely cues are shape and movement. It's like proof reading. You read once for sense, once for spelling, once for syntax, etc... It's not because a person is too stupid to recognize spelling or syntax erors in the same pass, it's that they are more efficient focusing on only one thing. It's the same with hunters, they will be looking for cues you may well be giving off. Off course, idealy they would make a proper ID before targeting you, but there are things that may mitigate against that. Like if the area is not considered to be multi use, etc...
The best thing you could do is make a lot of noise. I have a bear bell that velcros onto my bike for allerting pedestrians, that might help. Or running a radio loud.
You are at greater risk if you enter target areas from the back. So if you come off the railtrail, and enter the deep woods, rather than coming off roads. In the latter case you will not likely see all cars etc... indicating hunter presence as you enter the area.
