Distance versus intensity?
I can pretty much jog comfortably at 5 miles an hour for somewhere between 30 and 55 minutes, depending on the day. I do, however, get bored, and I feel like I'm not really challenging myself, so recently my plan has looked more like 10 minutes at 5 miles an hour, 5 minutes at six miles an hour, walk a few minutes, 15 minutes at 5 miles an hour, 5 minutes at six miles an hour, and I'm done. By that point I am pretty much entirely exhausted. My question is, is increasing the speed for a portion until I find that I need a break partway through less beneficial to increasing endurance than just running as long as I can at a lower speed?
