third loop was starting to get hard - pushed a lot agian on the very last one...
Nice how the max. HR increased over the intervals. Actually managed to reach my HR max at the very end of the last interval =)
Great training, has been some time since I did it last time. Got quite a lot faster since then (about 10" per loop). I guess on the track I could easily run 3:50, the finnish track loop iis quite twisting and thus slows me down.
But this interval makes certainly sense for orienteering. These are the reasons:
- twisting route: In orienteering you mostly run around trees etc. Not so much running straight. Thus de - and accelerating is important
- soft ground: pretty identical to forest ground (however, without all the branches and brambles)
- distance: 1.18km per loop. This is a farily long distance to keep up the pace, probably also about what you find in orienteering. You can easily run at the verge of acidity
So all in all a very good training. Definitely have to do it more often and try to get even faster =) (Loop below 4:30 would be the aim)

warm up and cool down (more or less running to the start and back home from the start). time inbetween the intervals not counted as I did the break just standing....
