5km as usual
i felt i'm quite fast at the beginning. but in the middle, pain in stomach again.but i thought i still maintained a good speed.
in the end, it's 31.57.51.
that's 156.45 m/min or 9.39 km/h or 2.61 m/s.
if i were to achieve my best speed, which is 165.71 min/s for 4.5 km, my time have to be 30.17 min.
so the target is now 30 minutes. looks difficult.
