My current PR is 11:40 which is obvious I could use a lot of improvement. I wanna run a 1.5 mile under 10:00 which I think is possible.
I'm asking because I just moved to New Mexico March 18 and where I am at is a higher elevation and my run time has taken a dive to 13:00.
Some problems I have is running out of breath quickly and not being able to keep a pace.
And I know I'm already skinny, but would cutting down to 170 pounds help improve my run?
