Sub 40 but a long way from sub 35

[Joemurray39:15]

Ran Glasgow morun yesterday. Bit of a disaster with regards planning, left with plenty of time but trying to go anywhere quickly with wife and twin girls is impossible. Then the obligatory visit to the loo took ages as they had decided to provide only 5 portoloos and it was nearly a half hour before I got in. Then it was straight to starting the race and I was halfway back with no warmup so my first k was quite slow. I was trying for sub 38 and had decided on 3:50/k with the hope I could finish strongly. The conditions were fine but I just didn't feel great and I had a stich pretty much straight away. Anyway my first lap was around the pace I was hoping for but km's 6-9 felt hard and I thought I had left it to late when I checked my watch with 1k to go, so I was pleasantly surprised that I managed to sneak in just under. I came 3rd but 1 and 2 came in around 36 minutes and 4 was half a minute behind me so I was pretty much on my own for the 2nd lap,
1.3:55 3:55
2.7:38 3:43
3.11:25 3:47
4.15:13 3:48
5.19:05 3:52
6.22:51 3:46
7.26:45 3:54
8.30:39 3:54
9.34.33 3:54
10.37:58 3:25

At the moment I'm planning a 5k on december the 9th and hopefully a 10k on the 29th of december in Ireland. Day 1 would fall on the 21st november. Obviously I'm doing the warmdown runs for the next three days, what should I do after that? Also what pace should I aim for the 2k's, 1k's etc.
