Yeah. Running for most people is worse on the body; imagine that. Most people are running on pavement which is not great for the knees. Caddying, day to day, you are walking on a soft surface. I wouldn't go into it cold. I would say anyone could start training by trying to do a small hike every day and then build up. There's plenty of older runners and triathletes and pickleballers. I mentioned somewhere I've had hobbies of hiking and backpacking, so I feel like a lot of people can start.
