Segments in fitness app

I use the fitness app on Apple Watch ⌚️ almost daily, usually outdoor walks or hikes. Usually it works fine. Occasionally it starts announcing that it has recorded a segment. I don’t really care about it most of the time. I think I understand what the segment function might be used for although I don’t think I would ever want to use it. Anyway, the problem is that sometimes it records ten or more segments in just a few seconds. Less commonly, sometimes when it does these flurries of segments it will then end my workout without saying that it is doing so. When that happens the resume workout function doesn’t work. So, I would like to turn off the segments function in the fitness app. Does anyone know how to do that? Thanks
