Treadmill 1% incline 1 mile warm up 8:00 This mile was the toughest mile of the whole run 6 miles at marathon pace 6:48 All 6 felt pretty easy 1 mile cool down 8:00 Over the last couple months I've been doing most my shorter tempo run on the treadmill and longer tempo runs outside. I've decided that it is takes a lot more effort to run on the TM at 1% incline than it is to run outside on fairly flat ground. Maybe it is that it is usually about 20 degrees warmer inside. I don't know, but all my longer tempo runs outside have felt way easier than my inside TM efforts. Good thing the marathon is outside. |
