RE: Ran a 1:55 800m yesterday...went out in 53. What could I have run with better pacing?
These trackbot estimates might work great for 1500+, but they're not going to give you a good answer for 800s.

Optimal 800 pacing is a ~2.5s lap differential,, but Trackbot's going to say my example below would be faster with even splits.

Trackbot! Optimize 800m 28.5 30 30 31
