Karlstad Stadslopp (2012)

Race #17 2012 - 10km - 40:36 [SB]

Karlstad Stadslopp (karlstadstadslopp.se).

Running towards a brighter future.



Back in Karlstad
Back in Karlstad with great people from SK Vidar this year as well. Check out my race report from 2011 here. Last year it was warm an humid, this time the forecast indicated a very wet experience. The good thing was that the rain never came so we could even sit in the sun and enjoy the "after-race-party" (bankett).

The Swedes were very happy to see us back in Karlstad and did celebrate.

Entering the hotel in style is always important. Mr RG won this time, but I will be back!

Mr Me.
Jack came second in his age group, Urige won the entire race and Dadafo came second overall.

Mr Buta getting ready for another run. He took it easy and finished in 29:33.

The temptations were many, however I waited visiting the bishop until after the race.

Jens-Kristian won his age group with the time 33:00.

Tone finished first of the girls, followed by Christina on second. 

Relax to the left, and to the right...

... there was bankett!



Capacity Planning
I had the impression that my negative experience from last year's race was an exception, and that the Swedes were far better at organising races than the Norwegians. After the brilliantly organised GöteborgsVarvet I definitively thought the Swedes were superior in terms of capacity planning of toilets, and the latter seems to be the case as well though.

At Karlstad there were 4428 participants this year, and the organisers had 15 toilets outdoor, 25 toilets indoor and 10 urinals indoor and outdoor. In total 50 toilets, which is not a bad number. However it is not good enough. According to the triathlete Kristin Lie an average pre race toilet visit takes 1:20 (yes, I actually did ask her for her opinion on the matter, and she has done some recordings of the results). If we add another 10 seconds to that average, for those not being as efficient, we can use 1 minute and 30 seconds as a sane average toilet time.

Assuming that 87.5%, or 3500, of all runners need to visit the toilet during the last hour we do get:
Arrival rate is: λ = 58.33 runners / minute.
Service time (toilet time) is: Rs = 1.5 minutes
The service rate (toilet visitors per minute) is: μ = 1 / 1.5 = 0.67 customers per minute
Wait time (max) we set to: Rw = 8.5 minutes (we want no one to wait for more than 8.5 minutes)
Response time: R = Rw + Rs = 8.5 + 1.5 = 10 minutes

Arrival rate for 8.5 minutes wait time is:
R = 1 / (μ − λ) ⇒ λ = (Rμ - 1) / R = (10*0.67 - 1) / 10 = 5.7 / 10 = 0.57

So there should be more than 0.57 customers per minute, however in Karlstad my estimates shows that there might have been 0.67 customers per minute. Another problem in Karlstad was that there were no toilets in close proximity to the start, so most people did use the surrounding areas / parks / gardens and what have you got. Not everyone knew about the indoor toilets either, hence the load on the outdoors once where higher than necessary. The result in Karlstad was long toilet queues and trashing. However it was far better than for example Sentrumsløpet 2012 in Oslo, that in comparison had more than 9000 runners and only 26 toilets (major fail in capacity planning). The start number pick-up and registration area seemed well organised though.

Time seems to be difficult for the organisers. According to their home page Tone ran in 32:09. OK, she is fast, but she was not that fast this time. Her official time was 34:09. And as last year several runners, including me, got times that were off.

My Race
Prior to this race I hadn't done a 10km (or longer) run since GöteborgsVarvet in mid May. This is due to my 400MP where I'm in stead spending several hours at the track running shorter distances. I'm used to keeping a better pace now compared to last year, but since my longest intervals has been 600m I was unsure how fast I could run a 10km. By the end of last year I managed to run the distance in 39:33 at Hytteplanmila, and I had a tiny hope that I would manage another sub 40 race now as well. Hence I decided to to start at a 4:00 - 4:05 pace just to see how it did feel and how far I could come in that pace. I even tried waking up my body with a pre race run on the day. Never done that before, I'll might do it again though cause it felt great.

I tried something new this time. A run a few hours before a race. (src: twitter)

Unfortunately I was far too passive at the beginning of the race and ended behind a lot of runners being heaps slower than me. Trying to run past them was not easy and when I reached the 3km sign in 12:40.5 I realised I had ruined a possible sub 40 run. However I decided to run faster the remaining distance and increased the pace. The next seven kilometres were completed in a 4:00 pace. According to my watch I completed in about 40:40. However Emit added some penalty seconds to my time this year, as last year, and  my official time became 40:54.1. The Emit timing system is not known for being accurate. Christopher, that started right in front of me and finished after me, got the official time 40:46.3. I think the formula is something like:
Accurate time = Emit time +/- 20 seconds.
At least it was a SB, even using the Emit time, and that is something.

UPDATE (19/6 2012):
After I contacted the organisers and told them my registered time being off they checked their systems and found that my correct time was 40:36.4.


One email and my time was shaved with about 18 seconds.

Several runners did very well today and SK Vidar did deliver overall. In the women's group Tone won and Miss C came second. In the men's group Urige won and Dadafo came second. Jack ran very well as well and came second in his age group. And Espen and his PB team also ran very fast.

  1. EMIT-tiden var ett sekund fra min egen klokke, så for min del stemte det :)

    1. Ja, og din tid stemmer ut ifra min klokke også. Litt kjedelig å få feil tid selv. Det samme skjedde meg, og en rekke andre løpere, i fjor. Emit visstnok kjent for å være unøyaktig.
