The lesson is, if I really want a good timing in a short run event, I must position myself at the front pack to avoid the 'cavalry surge' at the start. It was a massive jam!
But didn't feel I got a strong legs that day. Not having a luxury time. Damn... I keep running, but just can't run away from work! Work always catch up.
Time of 23m43s; ~4.23min/km.
