@pyrrhus: both. what i think is i lack proper nutrition training. my last full marathon has a conservative improvement of 5 minutes from the first one but the "injuries" that appear are worse than the first one (the first had only blisters, the second came in 3 - cramps, blisters, and achilles heel). my preparatory training are usually runs but more on the treadmill as i don't have much time to spend running outside juggling between work, training, and sideline.

@cro: guess my strength training helps.

@draex: i realized that in running long distances, there's a difference between getting proper hydration and keeping "hydrated". minsan kasi hirap huminga pag every water station e iinom ka.
