Marathon

Today is the day that i'm running Marathon, my first marathon. Haha.. Since this is my first marathon, i'm going for the 10k de. Before this day, i have been practising alomst every Sundays for nearly 3 months. During this training, i took about 75 minutes to finish, but after i ran, i found out that i took 90 minutes to finish the race.. WAD THE HECK!! WAD HAPPEN??
It was after then i found out that i have been running for about 12k.. -.- But anyway slow hur?
I don't really run fast as i'm not a good runner yet and have just start training only. Hope i can run more and more faster.. ^^
