Back in 2011, you may remember, the Birkie was held on a chilly day. The race started around ten below, and the temperature barely made it above zero later in the day, the lowest observed temperatures in the history of the race. Of course, it could be worse. On Monday, the high temperature in Hayward was -15. In other words, there’s a good reason why the race takes place in late February. There’s no way you could run the Birkie with temperatures varying either side of twenty below.
In any case, the temperatures in the Midwest have bottomed out, and look to increase in the next few days. By the end of the week, it could be nudging up in to the low 30s, a tropical paradise compared to 30 below. Luckily, temperatures don’t look to run any higher than that (aided by extensive snow cover) so the 12-to-18 inch base in Birkieland should be set for some time. And while it’s been dry recently, some snow appears on the horizon, to freshen that base, and add to it.
(Here in Boston, it’s been cold enough that they’ve blown in a mile of snowmaking and some of our higher-grade mental citizens are biking on the Charles.)
