Hi @REI-PearlD, what train running techniques do you suggest, like are there any videos? I used to use boots that I would run in from time to time but have switched entirely to trail sneakers. It was a huge improvement, but I'm still trying to figure out how to be more nimble when navigating terrain that has a lot of loose, sharp rocks. I've watched fast runners pass me by and try to mimic their turnover, but I need to do more work.
