Running intervals 16:00 [5] 4.0 km (4:00 / km)
first intervals of 2009! 4x1km w/ 2min rec. this was really slow, and hurt, a lot. but surprisingly not in my legs. seemed to be totally limited by my lack of ability to get enough oxygen into my body, which is probably related to not being able to get my heart rate up very high.
running felt a bit strange - legs were ok, but core muscles had no idea what to do, and upper body was a world of lactic pain. 1st and 3rd are slightly uphill.
