[QUOTE=danny_boy]Ok,
I have increased my run to 13k with no stopping. A friend who has ran 15 marathons told me his first marathn he would run 15-20mins and walk for 2 mins.
Has anyone heard of this sort of routine ?

Yes....
It is a good way of stamina building. The next step is to reduce the "recovery period" i.e. the walk and increase the run period.... etc
