4 miles, easy pace with a steady run for mile 3 (my split: 9:14, 9:00, 7:41, 9:15) , overcast & 57 degree. It should be obvious from my splits that I injected a steady run within today’s easy runs.
The easy runs were right on pace between 8:19 to 9:20. But the steady run pace was too fast* and pushing my current lactate threshold of 7:39 (making it like a tempo run). And I will not be able to handle the steady run later when its distance gets longer.
Since I am in base training, the purpose is to build my endurance. It makes sense for my steady run pace during this phase be closer to 8:22 (my current estimated marathon pace). So I can stay within the aerobic zone. Glad that I caught this mistake before I injure myself.
*A mistake on my part from reading the wrong chart.
