Saturday Night 10 K Time Trial

Just came back from the 10 K time trial.
I ran the route below 10 reps and finished in 43:10.72.
Each of the ten laps is as follows:
Lap 1: 4:14.00
Lap 2: 4:10.73
Lap 3: 4:16.41
Lap 4: 4:17.64
Lap 5: 4:23.31
Lap 6: 4.25.26
Lap 7: 4:25.78
Lap 8: 4.25.71
Lap 9: 4:22.42
Lap 10: 4.09.46
Total: 43.10.72

This is my second best time for the distance.
The good time is probably for two reasons.
One, the course is almost completely flat.
Two, I ran the inner edge of all bends and corners,
and that spared me tens of meters.
So I suspect that the real distance is slightly short of 10 K!

My next mission is one-hour jog scheduled for tomorrow.
It's going to be very slow, and mainly for relaxing my legs.
