I ran my intervals last night. They went very well. I started with an easy mile at 8:34 minute/mile pace. I took a two-minute rest interval. Then I ran the first interval which was 1 mile at 6:32 minute/mile pace. That went pretty well. I took a two-minute rest interval. Then I launched into my two-mile interval at 6:42 minute/mile pace. I have done this training schedule multiple times and had never managed to finish the two-mile interval without stopping to walk or catch my breath. Last night I managed to make it all the way through the two-mile interval with stopping. Then I took another two-minute rest interval. Then I launched into to 800m intervals at 6:15 pace. Each of those also had a two-minute rest interval. Then I did one easy mile cool down at 8:34 minute/mile pace. The work out felt really good. And I was really excited to have finished the two-mile interval!
