Another 10000m PB...

for the third time this track season I've somehow managed to set another 10000m PB...!

the stats:
start temp/humidity: 20.5/48%
start time: 7:34pm
total distance: 10.00
total time: 45:18.72
avg pace: 4:32
total calories: 803
avg HR*: 180

*Time spent in HR Zones:
00:05 [Z1: 93-111]
00:04 [Z2: 111-130]
00:06 [Z3: 130-148]
01:23 [Z4: 148-167]
32:57 [Z5: 167-185]

splits:
1:45, 1:49, 1:46, 1:47, 1:48 (2k - 8:55)
1:48, 1:48, 1:49, 1:49, 1:49 (2k/4k - 9:03/17:58)
1:50, 1:50, 1:50, 1:51, 1:52 (2k/6k - 9:13/27:11)
1:50, 1:51, 1:52, 1:50, 1:51 (2k/8k - 9:14/36:25)
1:52, 1:52, 1:49, 1:48, 1:33 (2k/10k - 8:54/45:18)

my planned pace was 1:50 with an aim of 45:50...very happy that my worst splits were only 1:52...had a couple of targets to chase - Carol M and in the last few laps Griffin who didn't even know I was there!
