First 2 miles non stop; time 30:00.

Ran: 2 miles
one additional mile of walk/run and included hills, dirt, asphalt and sprints.
Walked: 30 minutes

I decided to see if it's true that the first mile is the hardest and if a second wind doesn't occur until the second mile. Yes, I think it's true. I would have run three miles, but I didn't want to push it.
