Running 20:00 [4] 5.0 km (4:00 / km)
5 times 300m jog 246m, 5 times 400m jog 146m, 5 times 300m jog 246m. Was about the same pace when I ran a bit further for the middle ones (even though it was an attempt to reduce speed slightly to drag Åse along for the 300)... Hitting 300 between 1:10-1:14, and then the 400s about 1:37-1:38.
