Contrary to popular opinion, Boulder is not an ideal location to train between December and April. If you are starting your runs to and from campus, all warmups and cooldowns are on concrete. Retreat to dirt roads is futile as they often stay slick with packed snow/ice thus causing subtle stride changes. While it does get mild, frequent 0 degree cold blasts cause you to be stuck on concrete for 70 minutes as probably do not want to be out in the open prairie in the wind.
Not surprising for a lot of bone related injuries compounded by lack of sunshine causing low vitamin D, combined with hard surfaces reducing iron-count on top of strenuous training. A 35 year old who has given birth training hard I am not necessarily shocked.
Not a knock at the program, Wetmore is one of the best.
