Jakob halvmaraton

Without much training and without any time goal I participated in the Jakob half-marathon.

Up to 10 km things went smoothly. Then the steady uphill towards 11 km felt quite tough, although I sort of kept up the pace until about 14 km. From there it was a fight with a bit of walking now and then... The steady slow-down towards the finish shows in my 5k splits: 26:23, 27:25, 28:51, and 30:16. For comparison in 2012 on this course my 5k splits were: 23:47, 24:17, 24:20, and 24:09 - very steady and not slowing towards the end.

Here's a chart with the min/km times from the half-marathons I've run.

Next year I must remember to do one or two 90-120 minute training runs per month and things will go much smoother...

Jakob halvmaraton

I ran my 5th and fastest yet half-marathon in 1h 41min 52s (4:49/km) yesterday in Jakobstad.

Splits and pace for 5ks: 23:47 (4:45/km) , 24:17 (4:51/km), 24:20 (4:52/km), 24:09 (4:50/km)
Splits and pace for 10ks: 48:04 (4:48/km) , 48:29 (4:51/km)

The first 5k was maybe slightly too fast, but the last kilometer from 20k to 21k was the fastest, 4:43, so that shows there was plenty of energy in the legs at the end.

McMillan's calculator says a 1:42 half-marathon means a 10k should be doable in 45:45, and the full marathon distance in 3:35!

I ran this event in 2010 also.

Here's a graph of the km-pace for the five half-marathons I've run:

Stockholm Marathon

It was cold, wet, and windy!

Despite lack of proper preparation, a personal best with 4h 0min 34s. My long slow runs have consisted of only one 17k in April and one 22k in May. All the orienteering seems to help however, with the up/down hills giving more strength in the legs. Counting running+orienteering kilometers, I've done around 403k this year. Perhaps the four 60-100k bike rides I've done party give the training effect of a long run?

Splits for the first and second half:
0-21k: 1:57:53
22-42k: 1:59:18

Or broken down into 10ks:
1-10k: 56:49
11-20k: 55:18
21-30k: 56:19
31-40k: 57:49

Or broken down into 5ks: (compared to Rautavesi in 2011 and Helsinki in 2010)
1-5k:  28:54 (Rautavesi 27:13, Helsinki  29m)
6-10k: 27:55 (Rautavesi 27:46, Helsinki  30m)
11-15k: 27:37 (Rautavesi 27:29, Helsinki  30m)
16-20k: 27:41 (Rautavesi 27:23 , Helsinki  31m)
21-25k: 28:40 (Rautavesi 28:57 , Helsinki  33m)
26-30k: 27:39 (Rautavesi 31:09, Helsinki  34m)
31-35k: 29:51 (Rautavesi 31:27, Helsinki  36m)
36-40k: 27:58 (Rautavesi 35:17, Helsinki  40m)
