^^it's too dark for park running at night and it's a nice enclosed low traffic loop so I don't have to worry about traffic interrupting an interval.
over the next few weeks though the intervals get longer (up to 5x1km) so each session gets shorter than the week before as there's less recovery time in between, last weeks was pretty boring though (12x400m) but last night i did between 3-4 laps less (8x600m).
