This sounds very interesting ... a co-worker does it and it sounds like fun. I won't be able to attend this year but would be surprised if SBRA doesn't get some representation.
Here are the details on the ski-bike-run triathelon. It is a "short" tri - but challenging as the bike part has some very steep mountainous sections. There are age and team categories - very fun event, beautiful setting, it also included in race fee an evening dinner awards party.
