OK, not exactly backwards. I reversed my route in Jo'burg this morning. The advantage it gave me was a long (@ .7 mile) downhill before the last uphill (@ .6 mile). My overall time was faster than other runs this week -- 9:37 mpm. The Forerunner still showed a difference between the pace for total time (9:37 mpm) and for moving time (9:32 mpm). Not quite sure about that.
Run well, y'all,
