I'm new to running, and am on week 3 run 2. And actually enjoying it. Due to my working schedule, I'm wondering if it's problematic to swim laps on a run day. I also love to hike in the summer, but I'm wondering how to space that out with the runs since I live near the Canadian Rockies and my hikes tend to be fairly long and steep and are probably using/ exhausting the same muscles for running. Any insight would be appreciated.
