If I was in your shoes, I'd be doing a block of training to improve my 5 minute power. If you are able to do 5w/kg for 5 mins now (at a guess, I can't remember just how rediculously light you are), aim to get it to 5.5 and I bet you'd be able to stay with that group that drops you on the first climb.
