Foulées Hivernales 20k (19,2k)

Long time no post :)
since new year I started marathon training. Right now my goal is the Antwerp Marathon on the 22nd of April, but it will depend on my training. There are several other marathons around that time-frame, so I can shift a little if I want too.
Marathon training actually means just one thing: I run 4 times a week instead of 3.

Last sunday I ran my first 'longer' race in a long time, a 20k (19.2k to be exact).
I was kind of excited to see where my training was at. I didn't step down training the week of the 20k (except for not doing interval or tempo runs), so I wanted to know how I could perform if not fully recovered from training.
My race plan as usual was to run gently (around 5 min/km -> 12 km/h) the first 10k, and then step it up if I was able too.
The race was known to be hilly. Allthough indeed hilly, some of them steep, most hills weren't too long and recovery was going well after them.

so here are the splits:

3k: 15:17:90
4k: 4:48:56 (20:06:46)
5k: 5:03:37 (25:09:83)
6k: 4:56:07 (30:05:90)
7k: 4:58:02 (35:03:92)
8k: 4:54:04 (39:57:96)
9k: 4:52:75 (44:50:71)
11k: 9:25:27 (54:15:98)
12k: 4:39:36 (58:55:34)
13k: 4:38:74 (1:03:34)
14k: 4:34:48 (1:08:08)
15k: 4:38:72 (1:12:47)
16k: 4:29:92 (1:17:17)
17k: 4:31:32 (1:21:48)
19,2k: 8:53:60 (1:30:42)

final: 1:30:42
