I don't think this is fair. There is always a point at which cycling just won't work. For the American audience, -25C is -13F, and 15 km is 9.3 miles. That's a dangerous temperature unless you are dressed nearly perfectly. And one minor wipe out could leave you with ripped clothes and exposed skin.
You have to know your limits when dealing with the cold, especially this kind of cold. If you don't respect your cold-weather limitations, you could end up with frostbite (or worse).
I have never had to commute below 0F, so I won't try to out-macho this guy.
