While training for a marathon or half marathon, is it a good strategy to break up a long run over two days? For example, if I were to substitute a 10-mile long run on Saturday followed by a 3-mile recovery run on Sunday with a 7-mile run on Saturday and a 6-mile run on Sunday, would I be achieving the same adaptations?
