RE: Pacing: Quite possibly the toughest aspect of distance running

Slow and steady wins the race. Not really but at least you finish as strong as you start. In the army I did marathon training after the normal day exercises. I was just seriously hungry and saw they were fed different food which made it sound like a good idea. I am no serious athlete but we did 10km in 50-60 minutes every evening depending on the pace. If I did that now I would most likely collapse but 7 minutes per km sounds like a decent pace. Change your music selection.
