there is alot of stuff here which is way too indepth and over analysed for my liking. for what it is worth my longest ever training run is 2:15. never ever gone over that. moderate distances after biking will get you quicker.
in my experience the kms dont matter, in fact i have only ever ended up injured by the kms. for im it is about time and learning to run fatigued. you get to an im mara at 6 hours plus, your tired and now you have to run. the person who can run decently when their legs feel like utter shit will always outdo someone who hasnt trained for this.
so in saying this we need to run tired as much as possible, without risking injury. 4 hour runs = injury unless you have an extensive running history. what alex eludes to above, my focus was exactly this. i always ran 10km slightly above im pace off a 200 bike, and followed the next day with 120km then 20ish at im pace. the 20km were often really tough, but the form these end up being performed at was remarkably similar to the way i ran the im mara, because the workout were as specific to the objective as i could make them. i am not a good runner by any means but i was able to run faster than 95% because i knew what it felt like.
single sport analysis is just silly
