Testijuoksut
Choice of multiples of 3km... I went for 6km, as it was sufficient for a lazy shite on a Tuesday.
Set off with the lead group for a hundred metres or so, a lean, lithe bunch, then let them run off. Struggled along, breathing was not easy with the cold air and half-blocked nose. Several people passed me. 11:25 for the first lap, if my Finnish is fantastic. My total time may also be wrong :)
Surface was broad trail, with a shallow (I guess) layer of hard-packed snow. I wore trail-shoes, as did most, and they were pretty much fine.
Afterwards, went to the swimming pool to order 300 euros worth of clothes I won't get for three months.
