I ran 1.79 km in 7:48 last week. After that run, I heard an interview on the BBC where this person was doing a kilometre in 3 minutes. That is extremely fast. I doubt if I can make or sustain that when I was still in national service.
Yesterday, I ran 1.79 km in 8:20 and 5.2 km in 30:30. Not fast enough.
