All in all my summer so far:
***2 - 3 hours running a week with 3 hard running sessions.
***1 hard session in another(endurance) sport same intesity as the hard running(mostly cycling or glydex or rowing hard).
***some weightlifitng and other sports to stay in the move at low intensity,no point racing them i get enough fitness of those other 4 hard workouts.(if i swim i can do 5!)
***drink 1 litre of multi-vitamin juice after each hard session to recover from the 4(3-5) hard sessions.Further 8 hours of sleep a night an a nap.
That running is all inclusive,warm-up,cool down,breaks between reps,...
The other sports vary to what i want and can(at the moment i can swim as much) and i do them really easy except for that one session.
I might peak at the end of the summer and run 3.5 hours and increase my long run to 90 minutes and one easy run of 30 minutes above my 3 other hard running sessions.
A small sum says i trained 5 hours last week of wich 2.5 hours running.ANd 2 liftting sessions.THe rest was an easy ride,one swimming session.In total 3 hard sessions.
I tryed higher mileage before without to much success.
Even if im skinny and look like a marathonner and am a natural long distance runner
(didnt do well on the 100m school dash(15.5s) ,broke the school record on the 10 km dash--)41:00 10 km when i was younger ofcourse(and without training just a bit soccer on the playground like anyone else))
