Running 3:27  0.64 km (5:25 / km) +3m 5:18 / km
The first part of my jog to see how I felt, until I realised my HRM wasn't working.
Running 32:13 5.42 km (5:57 / km) +89m 5:30 / km
The rest of my jog. The answer - feeling much better! Legs a bit stiff from inactivity but lungs not too much of an issue.
Same Monday weights session.
