First 1/2-Marathon Pace 'Long' Run

Today I did my first 1/2-marathon paced 'long' run of this build phase. The pace should have been between 7:10 and 7:20 min/mile and I finished the 4.72 miles at a 7:12 pace which is excellent. It did feel difficult, but I have about 8 second to give on pace as a move the mileage up next week to between 5 and 6 miles. The per/mile pacing was even also: 7:13, 7:04, 7:17, 7:12 and 7:16. I think next week, I'd like to try and get the first mile in between 7:20 and 7:30 so that I have negative splits for once.
