Negatives, aka Negative Splits, is when you run a distance multiple times at increasing speeds.
For example, you may run 3 x 1 mile. You run the first in 8:00, the second at 7:45, and the third mile at 7:30. That is running negatives or negative splits.
I ran what turned out to be negatives today without planning it. My goal was to run 3 miles under 10 minute pace just to get some miles logged.
I started around 10 minute pace, but since it was so cool tonight, I decided to pick up the pace and started to get faster leg turnover. I got the second mile around 9 minute pace and then really started to force a faster arm swing which kept my momentum going until I finished up with a really strong kick with a fully opened stride. That last mile was under 8 minutes. I don't have exact times on my splits, because I don't have the streets painted. Hmmm... maybe I should do that. Just kidding.
After years of running, I can tell within 15-30 seconds how fast I've run a mile. Anyway, that's today's lesson. Negatives.
Warmup was 2 miles equaling a 5 mile total workout. And thank goodness for my new socks. I've never purchased them before, but I can vouch for Thorlo Pads. My feet felt great through the entire workout.
