I'd like to get these down

Thurs, 12/13-

Like this day five years ago, my plan was to do the 300s as I would do the pick-up reps workout: 8x400 @ 70, with #s 2,5, and 8 @ 63 with 3 minutes' rest.

For the 300s on the track, my target for the slower ones was 52-mid and my target for the faster ones was 47-mid.  My rest would be part walk/part jog back to the start in 2:30.

My runs:
#1: 51-low
#2: 48-low
#3: 51-low
#4: 53-low
#5: 48-low
#6: 53-low
#7: 51-low
#8: 45-low

Not bad, but I have more work to do. I'd like to get these down to 51 and 46, given the amount of rest I take. Alternatively, I could keep them at 52-mid and 47-mid with 90 sec to 2 minutes' rest.
