Two weeks of runs - getting faster

I reached a great milestone this week, ran 7 miles averaging less than 8 minutes per mile. Still walking 30 seconds per mile on distance and tempo runs, and those walks are in the times. Here are all the runs and their logs...​

April 20 - 7 miles at an 8:08/mile average - had a good run and beat the goal, averaging 8:03/mile according to Nike+'s record here.​

April 22 - intervals - four 3/4 miles at 5:13 each, with 1/4 miles resting between them. On intervals, I run 2 miles to warm up, and around 1 mile as a cool down. I managed to keep the pace close to the goal on the first two intervals and dropped 20 and 30 seconds on the uphill segments. Full details here.​

April 25 - Tempo run - 3 miles at 7:38/mile average - plus 1 mile warm up and 1 mile cool down. Almost did this - the splits on the three miles were: 7:18, 7:40, 8:03. So I did come pretty close! See the whole run here.​

April 28 - 7 miles at an 8:08/mile average - and here was where I went under 8 minutes per mile on average, actually averaging 7:57/mile! See it all here.​

May 1 - Intervals - 5 kilometer intervals aiming for 4:18/kilometer with quarter mile rests between them.​ I struggled with these, came close on 3, and dropped 20+ seconds on two. Not much to look at here, since the walks slow down the overall pace a lot!
