That’s how long I can jog at a stretch (or at least how long I jog at a stretch for this week’s C25k program).
Week 4, Day 1
Brisk five-minute warmup walk, then:
Jog 3 minutes
Walk 90 seconds
Jog 5 minutes
Walk 2½ minutes
Jog 3 minutes
Walk 90 seconds
Jog 5 minutes
Yeah, I know, boring. I just can’t get over the fact that I can run that much at a stretch—and I don’t have to drag myself upstairs with my elbows afterward.
