still effective to split miles between am &pm Melissa 8/27/09 1:30:07 PM ET
I am training for my first half marathon and need to do 5 miles a couple days a week but can't fit it in before work. Will I get the same training benefit if I do half of that days miles in the morning and the other half in the pm? Does it only "count" if the miles are run all at once?
