What a strange winter! I normally do a big trip abroad over the holidays, usually involving trekking and a bit of altitude. But this year I spent the holidays in Toronto nursing a bum knee where it was unseasonably mild, and then tried to make the most of what little snow we had back in Vancouver.
In late-December, I had managed to posthole through a tree well on a run to Kennedy Falls, which caused a strain and possibly a very minor tear to my MCL according to my physio. It felt okay to run on flatter terrain, but hurt to walk or extend my leg, and I had to stay off very technical terrain for a few weeks and cut back my training volume significantly.
