My first half-marathon is this Saturday. I did my last long workout on February 12th. The workout schedule listed an 11-mile, endurance pace run. I opted to run the route of the race I’m doing, minus a loop. I also made a few changes in strategy, and it really paid off: I felt better at mile ten than I did at mile two. Given that success, I decided my next long workout, a six-mile run, would be Badger. https://connect.garmin.com/modern/course/5405918
