Hi Riodog,
So, can you run for an hour and bike for an hour, both in Z2? Can you swim for 30mins?
If so you can start Fink's just-finish plan. You have plenty of time, so build it up or do a test week. Then if it works, tick over gently (tri club swims and bike sessions) until 32 weeks out (30 plus 2 in the bag for illness/work).
Then sit back, recover, say you'll never do it again. Rinse and repeat ad infinitum.
