Speed workouts on the treadmill are as much of a mental workout as a physical one! Five #yasso800s tonight at around three minutes and 30 each, with a 400-meter jog in between, plus a warm up and cool down. Why three minutes and 30 seconds? According to @bartyasso, creator of the workout, these intervals are supposed to predict your marathon time. So if you can run sets of 800s in 3:30, you’re supposed to be able to run a marathon in three hours and 30 minutes. And this has worked for me in the past! When I ran my 3:35 marathon in 2017, I trained by running my Yassos in 3:35. So we’ll see what I can do this time around! #speedworkout #marathontraining
