16x200m hill intervals, 1:30 off including the jog back down (so usually about 20s breather).
Trying to follow the Spari training schedule as close as I can, which was supposed to be 16x300m terain intervals, but difficult to find terrain within London, so the best/closest I could manage was a 200m incline with uneven surface and trees planted to add some uneven ground.
Difficult from the tracks to determine exact pace and exact climb covered due to GPS inaccuracy and short distance, but the intervals were managed with about a 4 min/km pace.
