depends on what you regard as your terrain for running... probably not great at road running but in forest terrain you will be going well. Stop doing yourself down and remember orienteering events are won in 5-7 mins/km which is slow for road or XC.
Also it's still very early season
As an orienteer who dabbles in both major terrain types I don't think there is a mainstream running surface that I am not interested in seeing how efficient I am at converting my fitness into speed on.
As for whether this was a disgraceful performance or not. I have not run either a lot, or at high intensity over the past month so I know my running specific fitness is not great. However, I don't think I have made any massively stupid decisions that have lead to this reduction in running so I feel I am off the hook on that as well.
So what non-mainstream running surfaces might you be interested in?

Well I thought that if I said I am interested in all running surfaces then some smart and irritating person would come along and ask why I am complaining about running on a bit of snow and ice in Oslo. I don't think I am interested in any non mainstream running surfaces. I am not a running hipster
