40:25/157
Was supposed to run 6.5 km (4 mi), but ended up going a smidgeon over 8 km (5 mi) so I wouldn't have to run through the mud with my new shoes, yet could turn around at a clear landmark and stay on the flats.
157 bpm represents just over 80% of my max. If I feel okay at the start, 78% is roughly the pace it feels like I could maintain forever. Maybe I should have as a goal running 8-minute miles for an hour at 78% of my max. (152 bpm).
