One long session vs. two shorter ones

[HappyGoLucky]

I'm wondering, what's more beneficial?
Running in the afternoon for about an hour, or running once in the morning for 30 minutes then another 30 minutes run in the evening?
Both are ran at the same speeds

It depends what you mean by "beneficial". Are you trying to build stamina? lose weight? gain a PB?

I'd say generally 2 shorter runs are better then one but then I'm coming from a 'lose weight' point of view, if your training for the marathon I's say one long run, get your stamina up, get yourself used to maintaining a speed for a longer amount of time, give your body plenty of time to rest and rebuild before the next time you chose to run.
But then I don't really know what your looking for.

Oh, sorry, from my point of view, losing weight/fat

2 short or 1 long run

If you run for 1 hour: during the 1st 20 minutes you burn 80% stored glycogen and 20% fat; next 20 minutes is 50/50 and last 20 minutes is 80% fat and 20% glycogen. So the last 20 minutes you burn a lot more fat for energy. 2 short runs and you burn 20% fat so it is less efficient if your goal is fat loss. My percentages may be off a little but you get the point.
