Apple Watch Ultra GPS tracking showing strange lines

[justacycler]

Hello! After testing my AWU on a cycling ride, I noticed that the map in the Fitness app shows a series of unusual straight lines all throughout my ride (see image for reference). The actual route is correctly mapped on top of them. Has anyone seen anything similar or knows what might be causing this? Thanks!

I don't know if it's related, but it might be an OS thing. I've been exercising at the two studios I go to daily (Barry's and a cycling studio), and the Ultra is reporting lower performance achievements.
