Doug‘s wife is an avid knitter and has become an avid podcaster. Her podcasts are typically about knitting with some local flavour from Duluth, MN, but her fifth podcast has a long section where she talks about snow biking in general and the Arrowhead 135 Ultra Race in particular. I found it very interesting hearing about this niche aspect of cycling from someone who is not a hardcore snow biker. I was a bit surprised how well she understands all the details and how supportive she was of the crazy winter ultra racing sport.
Definitely worth a listen…=-)
