I vomited for the 1st time ever.
I have poor planning on my nutrition.
Due to poor nutrition, I'm starving after 10km.
Due to starving, I'm start walking after 10km.
Due to hungry-ness, I drank 2 tins of milo.
2 tin of milo still not enough, I had my 1st ever meal during marathon.
Just before I'm entering into Burger King, I vomited all my milo.
After vomiting, I had my delicious Burger King.
I done a simple mistake which cost me all above.
Never ever run without power gel. Lesson learnt.
Timing: 7 hours 1 mins.
