For Florida set it at race pace and ride. It's flat.

Can't help on the technical questions re TR and Zwift, this will be my 6th (? i think) Oceanside, i've ridden the CT course and it doesn't translate at all, at least for me. Just don't ride too hard on the front side, there are a couple false flats that will sap your legs. The "hills" are short, but the worst for me is the section between hill 1 and hill 2, a rolling false flat that mentally is tough. At about 42 ish miles it's downhill and really fast to the last right turn on Camp P (mile 48 ish?) where you either get headwinds (likely) or if no winds continues to be fast

What I did for IMLP was to find someone who rode it, or look in the Best Bike Split courses and download the file out of there (after putting in the appropriate FTP and aero data to get your target time) and then drop it into workout creator. Pretty straight forward. Shoot me a message if you have Q's. Done this for a few races.

Great idea. Thanks. I can figure that out
