5 miles treadmill tempo, didn't have a lot of time before gym closed (early because of MLK day), so I hopped on and used the first mile as a "warmup" (ie, 5:52). Did the whole thing in 27:56, pace for first 4 miles felt sustainable for somewhere between 10k and 10 miles, but of course this is a treadmill, so it's slightly fast. Also, since I knew I only had time for 5 miles, I kicked it up in the last mile. I believe I figured out the mystery of why 5:00-flat mile repeats on the campus gym treadmills seem so easy, even on a small incline. Up until about 5:18 pace, each uptick made a noticeable difference in difficulty, but after this point, everything between 5:00 and 5:18 felt identical (tried to kick it up for a finishing sprint, but noticed that it didn't get any harder, so the treadmill probably just doesn't actually go faster than 11.3mph or whatever 5:18 is). Saw James Moore at the gym and waved as he walked by my treadmill but he looked confused. Hah. Splits: 5:52, 5:36 (11:28), 5:38 (17:06), 5:32 (22:38), 5:18 (27:56). |
