I also contacted Snow Card. Below is my email and the response I got.
So it appears that neither the BMC or Snow Card offer travel insurance that covers Ski Mountaineering racing abroad.

I was wondering if your this covered any any either your Single Trip or Multi Trip SKI/BOARD policies?
I'm unsure if it falls under any of below categories.
(Ski mountaineering racing being quite different from downhill ski racing (which I think the last category below is direct towards), being an endurance even like nordic ski racing, but in mountainous terrain)

BACK COUNTRY TOURING: covers remote ski touring using skins, often taking in overnight stays in mountain huts or travelling between resorts.
SKI MOUNTAINEERING: is the combination of alpine mountaineering taking in ascents of peaks with skiing and ski touring. The higher rated policies automatically cover the lesser rated styles of skiing or boarding.
RACE AND RACE TRAINING: amateur competitive skiing but not for full time members of national senior squads or competition at major international events.

Sorry for the delay in our response, unfortunately this is something that we are unable to quote for as It exceeds the limits of our insurance.
We would recommend the BMC as we are not able to cover this.
