Kristin! :) I do both...walking with friends and also running alone. I love BOTH...and for different reasons. The running (alone) has the interesting effect of making me highly aware of my body, which somehow helps me "feel" more. I think it's that there's nothing else to distract from my own feelings? Sometimes this means I feel teary but rather than crying, I run harder/faster when I feel that way, which is just as cathartic as tears, if not more. Walking with friends has become a really great way to connect and talk with friends. So I enjoy both!
