I've been using the Sufferfest novice program to increase my biking, I figured it would be an easy 10 weeks considering I've always through myself strong on the bike. It's been beating my *kitten* and there have been some very real performance increases.

Trainerroad is also an excellent app for indoor training and analysis.

Bricks are fun, but you would probably need to focus on building a good endurance base over a transitional comfort, so that would mean time on the bike, time in the running shoes, and most importantly, time in the pool.

I've been using the Total Immersion books as a point of reference for learning to glide and balance better in the water. That might be helpful. I also got a personal coach for the swim portion, and that helped a lot since swimming is very technique driven.

Finally, I would say, look around for local tri clubs, that might be a good resource. I've joined a local one, and I'm thinking of joining the local running/drinking club.
